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)
At room conditions 1 mole of gas occupies 24 dm3. How many dm3 are produced by 0.5 mol CO2?
Nitrogen dioxide ? dinitrogen tetroxide (2NO2 ? N2O4). If the forward reaction is exothermic, what happens to the equilibrium position when temperature is increased?
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?
25.0 cm3 of 0.100 mol/dm3 NaOH neutralises 40.0 cm3 of HCl. What is the concentration of the HCl?
For reaction A + B ? C, if you start with 0.20 mol A and 0.50 mol B, which is limiting?
A student obtains 3.00 g product when the theoretical yield is 4.00 g. What is the % yield?
A reaction’s theoretical yield is 12.0 g. The actual mass obtained is 9.00 g. What is the percentage yield?
10.0 g KClO3 decomposes: 2KClO3 ? 2KCl + 3O2. What volume of O2 (cm3) is produced (1 mol gas = 24 dm3)?
In 4Al + 3O2 ? 2Al2O3, 54.0 g Al reacts with 16.0 g O2. Which substance is limiting?
Copper compound A (blue) ? copper compound B (yellow) + water. The green equilibrium mixture will become more yellow if you:
