Nitrogen dioxide ? dinitrogen tetroxide (2NO2 ? N2O4). If the forward reaction is exothermic, what happens to the equilibrium position when temperature is increased?
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)
If 10.0 g sodium reacts with 10.0 g chlorine gas (Cl2) to produce NaCl (2Na + Cl2 ? 2NaCl), what mass of NaCl is produced (to 3 s.f.)?
A reaction’s theoretical yield is 12.0 g. The actual mass obtained is 9.00 g. What is the percentage yield?
A student obtains 3.00 g product when the theoretical yield is 4.00 g. What is the % yield?
After the reaction in the previous question, how much aluminium (in g) remains unreacted?
A mixture contains 0.200 mol A and 0.100 mol B reacting 2A + B ? products. Which is limiting?
30.0 g NO reacts with 30.0 g O2 via 2NO + O2 ? 2NO2. What mass of NO2 forms?
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?
3.00 g CH4 reacts with 4.00 g O2 to form CO2 and H2O. What mass of CO2 is produced?
10.0 g KClO3 decomposes: 2KClO3 ? 2KCl + 3O2. What volume of O2 (cm3) is produced (1 mol gas = 24 dm3)?
