Fuels and Combustion: Explanation, Formulae and Practice
Chemistry revision should combine definitions, balanced equations, observations and small numerical relations where applicable.
Useful Formulae and Rules
- Number of moles = given mass / molar mass.
- Concentration = amount of solute / volume of solution.
- For reactions, balance atoms on both sides of the equation.
- Acids have pH below 7, bases have pH above 7, and neutral solutions have pH 7.
Solved Example
Question: Find moles in 18 g of water. Molar mass of water = 18 g/mol.
Working: Moles = mass / molar mass = 18 / 18.
Result: Number of moles = 1 mol.
Unanswered Practice Questions
Try these yourself before checking notes or calculators.
- Balance: H2 + O2 -> H2O.
- Classify lemon juice, soap solution and pure water as acidic, basic or neutral.
- Find moles in 44 g of carbon dioxide if molar mass is 44 g/mol.
