One student draws a molecule as a flat displayed formula and another builds it as a ball-and-stick model. Which statement is correct?

Q: How do I try a free AQA Chemistry question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live AQA GCSE Chemistry bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for AQA Chemistry students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Chemistry questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Chemistry syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

One student draws a molecule as a flat displayed formula and another builds it as a ball-and-stick model. Which statement is correct?

Accepted Answer

Both are valid models; the three-dimensional one adds shape information the flat drawing cannot show — Award 1 mark. Models are judged by whether they are useful for the question being asked, not by whether they capture every detail.

Answer

Both are valid models; the three-dimensional one adds shape information the flat drawing cannot show

Answer

The three-dimensional model is wrong because it draws bonds as sticks

Answer

The flat drawing is wrong because molecules are not flat

Answer

Only one representation of a molecule can ever be correct
