50.0 cm3 of 0.200 mol/dm3 NaCl contains how many moles of NaCl?
2HCl + Ba(OH)2 ? BaCl2 + 2H2O. If 23.50 cm3 of 0.100 mol/dm3 Ba(OH)2 neutralises 25.00 cm3 HCl, what is the concentration of HCl in mol/dm3?
0.250 mol solute is dissolved in 500 cm3 solution. What is the concentration in mol/dm3?
2Na + Cl2 ? 2NaCl. If 46.0 g sodium reacts with excess chlorine, what mass of NaCl is formed? (Ar: Na 23.0, Cl 35.5)
If 12.0 g carbon reacts with 64.0 g O2 (C + O2 ? CO2), what mass of CO2 is produced? (Ar C 12, O 16)
2Al + 3CuSO4 ? Al2(SO4)3 + 3Cu. If you have 0.500 mol CuSO4, how many moles Al are required?
In Fe3O4 what is the percentage by mass of iron? (Ar Fe 56, O 16)
CH4 + 2O2 ? CO2 + 2H2O. If 10.0 dm3 O2 are consumed at RTP, what volume of CO2 is produced (RTP same conditions)?
2Mg + SiO2 ? 2MgO + Si. What minimum mass of Mg (g) is needed to completely reduce 1.20 kg SiO2? (Ar: Mg 24, Si 28, O 16)
A sample of product shows actual mass 24.6 g when theoretical mass was 30.0 g. What is percentage yield?
What is the limiting reagent and how many moles of CO2 are made when 1.50 mol NH3 reacts with 0.60 mol O2 in the reaction 4NH3 + 5O2 ? 4NO + 6H2O?
