Reacting_Masses_AQA_53_-_Foundation_Higher

Reacting masses is consistently the highest-tariff calculation on the Chemistry paper, and students need far more practice than a few textbook examples can provide. This AQA GCSE Triple Chemistry workbook builds step-by-step confidence with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What's inside:

- 12 progressive questions on Reacting Masses (using molar ratios from balanced equations)

- Structured EVERY method table on every question page

- Progressive difficulty: simple substitution, then unit conversions, then rearranging

- Self-assessment tracker with "What made me stuck?" reflection checklist

- Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 5.3 Quantitative Chemistry (Triple Chemistry only)

Reacting mass calculations require students to calculate moles of a known substance, use the balanced equation ratio to find moles of the unknown, then convert back to mass. This is a three-step minimum and examiners award marks at each stage.

Common student mistakes this workbook addresses: jumping straight from mass to mass without going through moles, using the wrong ratio from the balanced equation, not balancing the equation before starting, and losing marks by not showing each step of working clearly.

Suitable for AQA GCSE Chemistry (Triple only, not Combined Science). Works for both foundation and higher tier students.
