A 43.2 sample of CaCO3 was treated with aqueous H2SO4, producing calcium sulfate, 3.65 g of water and CO2(g). What was the % yield of H2O?

Tetraphosphorous hexaoxide is formed by the reaction of phosphorous (P4) with oxygen gas. If the reaction of 54.6 g of P4 with 28.6 g of O2 produces 21.0 g of P4O6, calculate the percent yield for the reaction.​

When table sugar is burned in presence of oxygen, carbon dioxide and water vapor are produced according to the unbalanced chemical equation: C12H22O11(s) + O2(g)→ CO2(g) + H2O(g)How many moles of oxygen are required to react completely with 6.75 mol of sugar?

In the reaction 2Al(s) + 3I2(s) → 2AlI3(s), the theoretical yield of the product is 12 g. When a student performed this reaction in his lab, he could obtain just 3 g of the product. Calculate the percent yield.

If a reaction actually gave 4.0 g of product instead of the predicted 12.0 g, calculate the percent yield.

When 25.0 g of CH4 reacts completely with excess chlorine yielding 45.0 g of CH3Cl, what is the percentage yield, according to CH4(g) + Cl2(g) → CH3Cl(g) + HCl(g)

The balanced equation tells us that 10 mol H2

Cardiac muscle is characterized by:

How many moles of oxygen will be produced by the decomposition of 7 moles of water?

The balanced equation tells us that 1.0 mol of Cu
