Question 1 · 1 mark · Difficulty 1/3

In a balanced chemical equation, the total mass of the reactants:

  1. Equals the total mass of the products
  2. Is greater than the products
  3. Is less than the products
  4. Is zero
Show answer & explanation
✓ Answer: AEquals the total mass of the products
Mass is conserved in a chemical reaction, so the total mass of reactants equals the total mass of products.
Question 2 · 1 mark · Difficulty 2/3

The limiting reactant in a reaction is the one that:

  1. Is completely used up first, stopping the reaction
  2. Is left over at the end
  3. Is the catalyst
  4. Has the largest mass
Show answer & explanation
✓ Answer: AIs completely used up first, stopping the reaction
The limiting reactant runs out first and determines how much product can form; the other reactant is in excess.

AQA GCSE Chemistry: Quantitative chemistry: reacting masses and limiting reactants FAQ

How many AQA GCSE Chemistry questions on Quantitative chemistry: reacting masses and limiting reactants are there on Kramizo?
Kramizo currently has 15 exam-board-aligned practice questions on Quantitative chemistry: reacting masses and limiting reactants for AQA GCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Quantitative chemistry: reacting masses and limiting reactants practice with other Chemistry topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Quantitative chemistry: reacting masses and limiting reactants questions aligned to the official AQA GCSE Chemistry syllabus?
Every question is written against the published AQA GCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Quantitative chemistry: reacting masses and limiting reactants typically tested on AQA GCSE Chemistry papers?
Quantitative chemistry: reacting masses and limiting reactants appears across multiple question types on real AQA GCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
