C + O2 →   CO2

If 15.0 g of C reacts with lots of O2, then what is the theoretical yield of CO2? If 38.2 g of CO2 is actually produced then what is the % yield?

C2H6 + O2 →   CO2 + H2O

If 175 g of C2H6 is burned in lots of oxygen, what theoretical yield of CO2 and H2O

NH3 + NO → N2 + H2O

How many moles of each reactant were there if 13.7 moles of N2 is produced?

Al +Cl2 → AlCl3

When 80 grams of aluminum is reacted with excess chlorine gas, how much AlCl3 is produced?

Sb2S3 + Fe → Sb + FeS

If 3.87×1023 particles of Sb2S3 reacts with excess Fe, what mass of FeS is produced?

CO + H2 → CH3OH

At STP, what volume of H2 is needed to react completely with 8.02×1023 molecules of CO?

H + O2 → H2O

What mass of oxygen is needed to burn 1 gram of hydrogen, and what mass of water is obtained?

If B2H6 + O2 = HBO2 + H2O

What mass of O2 will be needed to burn 36.1 g of B2H6? How many moles of water are produced from 19.2 g of B2H6?

What is the mass (in Kg) of water produced when 3.8 L of gasoline (C8H18) combusts? The density of Gasoline is 0.79 g/ml.

H2 + O2 = H2O

How many moles of O2 are needed to react completely with 2.00 moles of H2? How many moles of H2O are made after complete reaction of 2.00 moles of H2?

NH3 + O2 = N2O + H2O

How many moles of O2 are needed to react completely with 3.00 moles of NH3? How mnay moles of H2O are produced after complete reaction of 3.00 moled of NH3? How many moles are produced after cp,[plete reaction of 3.00 moles of NH3?

C + O2 = CO2

What is the theoretical yield of CO2 in grams? If 38.2g of CO2 are actually produces, what is the percent yield of the experiment?
