Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad added small pieces of four different metals to dilute hydrochloric acid and recorded the observations. Which result indicates the MOST reactive metal?

  1. No bubbles observed
  2. Slow, steady stream of bubbles
  3. Rapid bubbling with heat released
  4. Metal sinks to the bottom
Show answer & explanation
✓ Answer: C — Rapid bubbling with heat released
Award 1 mark for identifying that vigorous reaction indicates high reactivity. A is incorrect — no bubbles suggests an unreactive metal like copper. B is incorrect — slow bubbling indicates moderate reactivity. D is incorrect — sinking is related to density, not reactivity.
Question 2 · 1 mark · Difficulty 2/3

In the bauxite refining process in Jamaica, aluminium is extracted from its ore using electrolysis rather than carbon reduction. Which statement best explains why carbon cannot be used to extract aluminium from aluminium oxide?

  1. Carbon is less reactive than aluminium
  2. Carbon is more reactive than aluminium
  3. Carbon does not conduct electricity
  4. Carbon is too expensive to use
Show answer & explanation
✓ Answer: A — Carbon is less reactive than aluminium
Award 1 mark for recognising that a more reactive element is needed to displace a less reactive one. B is incorrect — carbon is actually less reactive than aluminium in the reactivity series. C is incorrect — carbon does conduct electricity but this is irrelevant to reduction. D is incorrect — cost is not the chemical reason for using electrolysis.

CXC CSEC Chemistry: The Reactivity Series of Metals FAQ

How many CXC CSEC Chemistry questions on The Reactivity Series of Metals are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on The Reactivity Series of Metals for CXC CSEC 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 CXC 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 CXC CSEC 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 The Reactivity Series of Metals practice with other Chemistry topics or even switch to a totally different CXC 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 The Reactivity Series of Metals questions aligned to the official CXC CSEC Chemistry syllabus?
Every question is written against the published CXC CSEC Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC 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 CXC.
How is The Reactivity Series of Metals typically tested on CXC CSEC Chemistry papers?
The Reactivity Series of Metals appears across multiple question types on real CXC CSEC 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.
