Question
- A. Methane + Oxygen → Carbon Dioxide + Water
- B. Carbon Dioxide + Water → Methane + Oxygen
- C. Oxygen + Methane → Carbon Dioxide
- D. Methane → Carbon Dioxide + Water + Oxygen
Answer
The correct option is Methane + Oxygen → Carbon Dioxide + Water.
Explanation
The correct option is Methane + Oxygen → Carbon Dioxide + Water. Methane + Oxygen → Carbon Dioxide + Water is correct because it directly supports the approved learning objective to write word equations for reactions in the Chemistry specification. This is tested in the subtopic Atoms, elements and compounds within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes, so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Atoms, elements and compounds precisely. Repair marker 6d7854d9 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Common Mistake in Writing Word Equations
Students often forget to include the correct reactants and products in word equations, leading to incomplete or incorrect representations of chemical reactions.
To fix this, carefully identify all reactants and products involved in the reaction and ensure they are accurately represented in the word equation.
