Limiting Reagents

5.51: Which Reagent is restrict and How Much Precipitate is formed? SCH-3UI-03 David Yu Mrs. Hatton Due involvement: May 5, 2012 Cut-Off Date: May 12, 2012 Purpose: To experience and livid plague what you have learned in class slightly hydrometric stoichiometry by predicting and determining the circumstances 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 number of entities. A mole is a service adequate amount of chemicals that is practical to use. The molar pickle of a compound or atom is the mass of 1 mole of anything; this is sexual relation to the atomic mass from the semestral table. The percentage expect from an try would be the actual yield divided by the supposititious yield multiplied by 100. We need to know how to symmetry chemical equations ascribable to honor of conservation of mass. Being able to turn moles into mass and mass into moles th rough the equation m=nM rearranged to find place other components. 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 volition be the strontium chloride due to the calculations and the copper (II) sulphate pentahydrate. My calculations besides conclude that we should get 1.378 g of the precipitate of strontium Sulphate.
