balanced Chemical reaction is as follows;
P4 + 5 O2 => 2 P2O5
then
P4: 112 g = 112 g/ 124 g/mol – 0.903 mol
O2: 112 g = 112 g / 32 g/mol = 3.5 mol
the,calculate the amount of P2O5 produced.
2.5 mol of O2 will react with 0.7 mol of P2O5 to produce
1.4
mol of P2O5.So,
1.4 * (31*2 + 16*5) = 198.8 g

In the following chemical reaction, 2 mol of A will react with 1 mol of B to produce 1 mol of A2B without anything left over: 2A+B→A2B But what if you're given 2.8 mol of A and 3.2 mol of B? The amount of product formed is limited by the reactant that runs out first, called the limiting reactant. To identify the limiting reactant, calculate the amount of product formed from each amount of reactant separately: 2.8 mol A×1 mol...

A Review | Constants Periodic Table Correct Learning Goal: To calculate theoretical and percent yields, given the masses of multiple reactants. A balanced chemical reaction gives the mole ratios between reactants and products. For example, one mole of white phosphorus, P4, reacts with five moles of oxygen, O2, to produce two moles of diphosphorus pentoxide, P205: Part B What is the maximum number of moles of P2O5 that can theoretically be made from 144 g of O2 and excess phosphorus?...

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...
