Worked Solution & Example Answer:Which products are formed when magnesium reacts with steam? A - AQA - A-Level Chemistry - Question 19 - 2018 - Paper 3
Step 1
C. Magnesium oxide and hydrogen
Answer
When magnesium reacts with steam, it undergoes a chemical reaction that produces magnesium oxide and hydrogen gas. The balanced chemical equation for this reaction is:
ightarrow 2MgO + H_2 $$ Here, magnesium (Mg) reacts with water (H₂O) to form magnesium oxide (MgO) and hydrogen gas (H₂). Thus, the correct answer is option C.
