Limiting Reactant Effect on Lab

Limiting Reactant Effect on Lab The Limiting Reactant Lab ABSTRACT The purpose of is lab is to see how the limiting reactant effects the whole lab. To determine what the other limiting reactant was and how much of reactant was there. INTRODUCTION A[CS4] limiting reactant limits the reaction and controls the amount of product formed when balancing an equation and making calculations. When calculating a limiting reactant, two reactant masses given because once the limiting reactant is gone the reaction stops producing. Limiting reactant is the reactant that is completely used until there isnt any more of it and then the reactant will stop. (Shah, 2007) (Buthelezi, Dingrando, Hainen, Winstrom, Zike, 2013). Hypothesis is proposed that if there is a sufficient amount of iron that the copper would not be precipitated. MATERIALS Ring Stand Filter Paper Distilled Water Stirring Rod Pipestem triangle Balance Copper(II) sulfate 100mL beaker Wire screen Weigh cups Iron filings 250mL beakers Bunsen burner METHODS The mass of 100mL beaker was measured using a balance. The mass of the weigh cups were taken using a balance, also. 8 grams of copper sulfate crystals were measured using a balance and placed into the 100mL beaker. A graduated cylinder was used to measure out 50 mL of water out to add into the crystals. A Bunsen burner was lit under the ring stand with the wire screen on the ring clamp holding the 100mL beaker and substances in place. The beaker was heated and stirred until just before it began to boil, then the gas was shut off to stop the flame [CS5]and the solution began to cool. 1.3 grams of iron filings were stirred into the hot copper sulfate crystals. The 100mL beaker was left to cool for ten minutes while observing the reaction taking place. A sheet of filter paper was taken including initials written [CS6]on it and weighed. A filtration system was made and placed into a funnel. The funnel was placed over an E[CS7]. flask. The liquid was poured slowly into the funnel going th rough the [CS8]filter paper and into the flask. With tap water the beaker was rinsed. When the solid settled[CS9], the beaker was rinsed two more times, until all of the solid was transferred to the filter paper. The filter paper was placed onto a watch glass and then placed into the oven. Once it is cooled[CS10], the mass of the beaker, filter paper and solid were recorded. RESULTS The[CS11] Limiting Reactants limit the reaction. Once the limiting reactant is gone[CS12] the reaction stops, it determines the amount of the product being produced. Single replacement reaction is a chemical reaction happens when certain atoms in one replace the atoms in another element[CS13]. If[CS14] you dont[CS15] balance and record your numbers then you cannot keep track of how much you have, and then it can make you[CS16] to use too much or to less of needed for the chemical reaction. Using dirty glass wear[CS17] can affect the weights[CS18] and the reaction occurring[CS19]. Mass[CS20] of empty 100mL beaker 70g Mass of copper (II) sulfate 8.0g Mass of iron filings 1.3g Substance collected 3.0g Mass of filter paper 2.0g Moles[CS21] of copper (II) sulfate equaled out to be 0.08 moles because 8.0 grams of copper sulfate multiplied by one mole of copper sulfate divided by 96g of copper sulfate equaled 0.08 moles. The amount of iron added to the solution calculated out to be 0.02 molFe because 1.3 multiplied by one mole Fe divided by 56 grams Fe equals 0.02molFe. There were 0.05 moles of substance produced due to 3 grams being multiplied by 1 and divided by 64 grams and equals to 0.05 moles of substance. Moles of iron metal reactant came out to be 2.8 moles because 8 grams multiplied 1 mole divided by 160 grams multiplied by 56 grams equals 2.8 moles. Copper (II) sulfate starts with 3 grams divided by 56 grams multiplied by 160 grams equals 8.57 moles CuSO4[CS22]. [CS23]The limiting reactant is the iron metal. Its the lowest number[CS24]. The CuSO4 was the excess due to having more left over an exact amount of 8.57 moles. The only error [CS25]that occurred in the lab would be the beaker not being quite as clean as needed In correct recording[CS26] of the Iron[CS27] filings. Also[CS28] that Some[CS29] of the iron was still built up along the sides of the beaker[CS30]. Some of the iron came out [CS31]before it reached the beaker with the copper (II) sulfate. [CS1]APA format says that the running head should be left aligned and page number right aligned. The title of your lab should also be in all caps. [CS2]Please do not use . Either use a comma or the word and. [CS3]Your abstract is missing. Please create a new page, make a center and bold heading Abstract, and complete. Your abstract should be a summary of the purpose of the lab and your findings. [CS4]Paragraphs should be indented. [CS5]Shutting the gas off stopped the flame. Please be specific and explain that instead. [CS6]Third person [CS7]Spell out the name. [CS8]And would work here also [CS9]comma [CS10]comma [CS11]The first line of the paragraph is indented only. [CS12]comma [CS13]Please clarify. [CS14]Just so this lab report will flow a little better, please put a sentence here about potential errors could have been caused by these things in the sentences that follow. [CS15]Please dont use contractions. [CS16]Third person, please. Try something like it would be possible to à ¢Ã¢â€š ¬Ã‚ ¦. [CS17]This should be spelled ware. [CS18]masses [CS19]If you say this, you need to explain how. Dirty glassware causes masses to be falsely increased due to contaminants or side reactions that use up the reactants to make an undesired product. [CS20]Put in a heading to label this table as Table 1. It should be bold and left aligned. [CS21]Please left align [CS22]This needs subscript. [CS23]This is very difficult to read. Please see me for correct format. Also, instead of going by the calculations listed in the form, calculate limiting reactant and excess in grams the way we did in class. [CS24]Instead of this, it needs to be specific. The limiting reactant was iron metal since calculations indicated that the smallest amount of copper could be produced. [CS25]Many errors are possible. Please mention incorrect measurements, faulty balances, side reactions due to dirty glassware. [CS26]Incorrect is one word [CS27]This does not need to be capitalized. [CS28]comma [CS29]Do not capitalize [CS30]Remained in the beaker [CS31]Came out? How did it come out? Be specific. Mention sticking to the weigh boat, spilling, or some other means of losing the iron.

Interpersonal Needs, Firo

Fundamental Interpersonal Relationship Orientation Interpersonal, FIRO, are the relations between people. Each party takes account of the other; behavior is affected by the other or determined by expectations of another. Interpersonal Behavior, otherwise known as FIRO-B, refers to a person’s feelings and actions. People join groups to satisfy interpersonal needs. Interpersonal needs are based on self-image. Being a distinct person – having a particular identity, happens and shows early in the group formation process.Our needs to be included help drive how we communicate, three basic human needs are Inclusion, control and affection. Inclusion The need to matter so people will care about you. Refers to feeling of importance to the extent to which we include ourselves with others. Inclusion reveals itself in people that want to be attended to, wanting to attract attention and/or wanting interaction with others. People with low inclusion needs tend to be introverted and wit hdrawn.An example would be; â€Å"No one is interested in me, because I am worthless, I’m not going to risk being ignored, so I will stay away. † Control Refers to feelings of competence, being seen as able to cope with the world, to the extent of which we control other’s actions or desire for them to guide us. If inclusion is about belonging, then control is about winning. A person seeking inclusion wants to be part of the argument, win or lose. One seeing control wants to win, even if he’s not accepted by the group. Control also deals in areas of power, influence and authority.Someone in the extremes of control needs, desire the control over others – and over one’s future, or the desire to be controlled – to have responsibility lifted The person who will not take responsibility for anything, an example, â€Å"Whatever you say boss. † Affection Refers to the feeling of being lovable, definition in your text is simplistic. An a mount to which we express affection to others and desire that from them. Close emotional feelings between two people – only between two people. Inclusion needs and control needs can exit between dyads or etween one person and the group. Last phase to emerge in human relationship Conclusions Inclusion is about prominence, control is about winning and affection is about interpersonal relationships. In inclusion phase people encounter each-other and decide if they will continue the association. In control the confront each other and work out how they will be related. In order to continue the relationship, affection ties must form and people must embrace each other to form a lasting bond, and also say goodbye. Control deals with power while affection deals with emotional ties.Get down to business vs. get to know each other.

Que es WIC y como solicitar esta ayuda para nutrición

WIC es un programa de ayuda para que embarazadas, lactantes, mamà ¡s recientes, infantes y nià ±os menores de 5 aà ±os  puedan adquirir alimentos y asà ­ asegurar una buena nutricià ³n. En este artà ­culo se explica quià ©nes pueden beneficiarse, cà ³mo solicitar esta ayuda y sus posibles efectos migratorios. Quà © personas pueden calificar para esta ayuda Mujeres embarazadasMujeres que alimentan con leche materna  durante el primer aà ±o del bebà ©Mujeres que recià ©n tuvieron a su hijo durante los seis meses  siguientes al parto o finalizà ³ el embarazo y que no alimentan con leche maternaInfantes menores de un aà ±oNià ±os/as menores de cinco aà ±os Quà © requisitos de ingresos se piden Este beneficio es para las personas mencionadas que tienen pocos ingresos. Pero,  ¿cuà ¡n pocos? La respuesta es que depende del estado en el que se vive. La ley federal  Ã‚  dice que pueden beneficiarse las personas que vivan en un hogar familia con ingresos inferiores al 185 por ciento de lo que cada aà ±o se establece  como là ­nea de la pobreza. Sin embargo, algunos estados permiten recibir estos beneficios aunque se tengan ingresos superiores, como por ejemplo el 100 por 100 de la là ­nea de la pobreza, por lo que hay que comprobar la norma que aplica. Ademà ¡s, si se recibe ayuda por otros beneficios como por ejemplo Medicaid, TANF o SNAP se puede calificar automà ¡ticamente para WIC. Quà © requisito de estatus migratorio es necesario para calificar para WIC No es necesario tener estatus migratorio legal (es decir, pueden aplicar los indocumentados). Tampoco es necesario ser residente permanente ni ciudadano. Otros requisitos para calificar para WIC Todos los aplicantes de WIC deben pasar consulta y someterse a un anà ¡lisis de sangre con un nutricionista, mà ©dico o enfermera, que es quien tienen que declarar que dichas personas està ¡n en situacià ³n de riesgo nutricional. Por ejemplo, porque pesa menos de lo considerado normal, tiene anemia, sigue una dieta pobre y no saludable o, en el caso de mujeres embarazadas, tienen un historial de embarazos problemà ¡ticos. Ademà ¡s, durante el proceso de certificacià ³n se verificarà ¡ si los nià ±os e infantes han recibido las vacunas mà ­nimas. En el caso de que su calendario de vacunacià ³n no està © completo se le referirà ¡ a un centro sanitario para recibirlas. Recibir el WIC,  ¿puede perjudicar para otro tipo de beneficios migratorios? Este punto es importante porque las autoridades de Inmigracià ³n o los consulados pueden negar a una persona:  si se considera que dicha persona puede convertirse en una carga pà ºblica (public charge, en inglà ©s). Por lo tanto, en estos casos se podrà ­a poner en riesgo situaciones como: la aprobacià ³n de una visala autorizacià ³n para reingresar a los Estados Unidosla aprobacià ³n de la tarjeta de residencia (green card)adquisicià ³n de la ciudadanà ­a mediante el trà ¡mite de naturalizacià ³n. Pero es muy importante tener claro que WIC no afecta a la declaracià ³n de carga pà ºblica. Es decir, se puede solicitar y aceptar este beneficio, siempre y cuando se cumplan los requisitos, sin temor a que afecte en el futuro en asuntos migratorios.   Esto es asà ­ tambià ©n en otro tipo de beneficios pà ºblicos en los que no hay entrega de dinero, como por ejemplo cupones de alimentos (food stamps) o vivienda pà ºblica. Quà © se puede recibir si este beneficio es aprobado En la mayorà ­a de los estados los beneficiarios reciben cheques, vouchers o una tarjeta (EBT) para la compra de determinado tipo de alimentos como por ejemplo leche, huevos, jugos, peanut butter, cereales, frà ­joles, vegetales, fruta, pan integral y comidas para bebà ©s. Si bien esta forma de acceso a WIC es la mà ¡s comà ºn, en algunos estados todavà ­a se distribuyen cajas de alimentos entre los beneficiados. En algunos casos hay que ir a buscarlas a un almacà ©n, en otros se envà ­an a las casas de los beneficiarios. Ademà ¡s, se intenta potenciar la lactancia materna, mediante ayuda para enseà ±ar los mejores mà ©todos para practicarla y tambià ©n alargando el tiempo que se puede recibir este beneficio para las madres que alimentan a sus bebà ©s con su propia leche. Sin embargo, cuando à ©sta no es una opcià ³n se puede comprar fà ³rmula para lactantes, que tiene que ser la marca que establece cada estado.   Cà ³mo se solicita el WIC Se aplica en el estado en el que se reside y en la oficina que corresponde al lugar de residencia. Aquà ­ està ¡ la lista de telà ©fonos gratuitos a los que marcar en cada estado para solicitar una cita. Ademà ¡s, aquà ­ està ¡ la lista de la oficina central en cada estado, con correo electrà ³nico para comunicarse y enlace a la pà ¡gina oficial estatal, con los sus requisitos (incluye Puerto Rico y otros territorios, el Distrito de Columbia y las tribus de las naciones indà ­genas). A tener muy en cuenta En ocasiones, a pesar de calificar no se puede recibir el WIC. Esto es asà ­ cuando en una agencia local que gestiona este programa se ha llegado al là ­mite permitido. En estos casos se establece un sistema de prioridades sobre quià ©n debe recibir la ayuda y quià ©n no. A consecuencia de ello, algunas personas podrà ­an quedar excluidas. Segà ºn los à ºltimos datos, el aà ±o pasado se beneficiaron de este programa 7,696,439 personas. El coste del programa en el à ºltimo aà ±o fiscal, pendiente de datos finales, fue de $1,946,286,967 incluidos gastos de alimentacià ³n y administrativos. De interà ©s para padres y madres En Estados Unidos està ¡ estadà ­sticamente demostrado que la calidad de la educacià ³n que recibe un nià ±o es muy importante para su futuro. Por esta razà ³n se recomienda informarse sobre los aspectos bà ¡sicos de cà ³mo funciona el sistema educativo y cuà ¡les son las opciones. Este es un artà ­culo informativo. No es asesorà ­a legal.
