A sample of 94.9 g
94.9 g of tetraphosphorous decoxide (P4O10) reacts with 68.0 g
68.0 g of water to produce phosphoric acid (H3PO4) according to the following balanced equation.
P4O10+6H2O⟶4H3PO4
Determine the limiting reactant for the reaction.
Calculate the mass of H3PO4 produced in the reaction.
Calculate the percent yield of H3PO4 is isolated after carrying out the reaction.
The reaction goes to completion, but in the process of washing and drying the precipitate, some was lost. The percent yield for the reaction is 79.9%
79.9%. How many grams of precipitate are recovered? How many grams of the excess reactant remain? Assume the reaction goes to completion.
An aqueous solution containing 7.11 g
7.11 g of lead(II) nitrate is added to an aqueous solution containing 6.53 g
6.53 g of potassium chloride.
Enter the balanced chemical equation for this reaction. Be sure to include all physical states. What is the limiting reactant?
The reaction goes to completion, but in the process of recovering the product, some of it was lost. The the percent yield for the reaction is 82.2%.
82.2%. How many grams of product are recovered?
How many grams of the excess reactant remain? Assume the reaction goes to completion.
