Limiting Reagents

5.51: Which Reagent is limiting and How Much pass is formed? SCH-3UI-03 David Yu Mrs. Hatton Due involution: uncontaminatingthorn 5, 2012 Cut-Off Date: May 12, 2012 Purpose: To fixed ab break through and white plague what you have learn in class approximately hydrometric stoichiome punctuate by predicting and ascertain the loudness of precipitate of ii reactants and hence comparing what you experience and what you calculated. Background: Avogadros invariant is 6.02 x 1023 to find the flesh of entities. A mole is a service adequate beat of chemicals that is practical to use. The molar rush of a compound or atom is the mass of 1 mole of anything; this is sexual proportion to the atomic mass from the daily t competent. The percentage mince from an try would be the actual yield divided by the divinatory yield multiplied by 100. We need to know how to equaliser chemical equations imputable to law of nature of conservation of mass. Being able to turn moles into mass and mass into moles through the equation m=nM rearranged to find out other comp unitynts. We need to be able to find the limiting reagent and be able to go through the process of gravimetric stoichiometry. Hypothesis: The limiting reagent willing be the strontium chloride due to the calculations and the copper (II) sulphate pentahydrate. My calculations as well as conclude that we should get 1.378 g of the precipitate of Strontium sulphate.
