Gas volume question: 0.125 mol of gas at RTP occupies how many dm3?
A reaction has a maximum theoretical mass of product 20.0 g but the actual mass obtained is 16.0 g. What is the percentage yield?
When 4.68 g hydrated CuSO4 loses water to give 2.99 g anhydrous CuSO4, what is the maximum mass of water that can be produced from 11.70 g hydrated CuSO4?
If you start with 5.00 mol H2 and 1.00 mol O2 for 2H2 + O2 ? 2H2O, which is limiting?
If 2.00 g Ca reacts with excess HCl to produce H2, what volume (cm3) of H2 at RTP (24 dm3 per mol) is produced? (Ca ? Ca2+ + 2e–, 2H+ + 2e– ? H2)
A reaction’s theoretical yield is 12.0 g. The actual mass obtained is 9.00 g. What is the percentage yield?
If 3.00 g Na (molar mass 23.0) reacts with 3.00 g Cl2 (molar mass 71.0) to form NaCl, what mass of Na remains unreacted?
In 4Al + 3O2 ? 2Al2O3, 54.0 g Al reacts with 16.0 g O2. Which substance is limiting?
10.0 g CaCO3 ? CaO + CO2. What is the theoretical mass of CaO produced? (Ar: Ca 40.1, C 12.0, O 16.0)
Treat 10.0 g of CaCO3 to give CaO + CO2. If the CaO is 5.61 g theoretical, what is percent atom economy for producing CaO from CaCO3? (atom economy = (Mr desired product ÷ Mr reactants)×100)
Given A + 2B ? C, if you start with 0.50 mol A and 1.00 mol B, which statement is correct?
