This is a list of metals in decreasing order of reactivity:
Sodium, calcium, magnesium, zinc, iron, lead, copper, gold.
(i) Name one metal that reacts slowly with dil. sulphuric acid.
(ii) Name two products of this reaction.

Explanation

To solve the question step by step, we will address both parts of the question regarding the reactivity of metals with dilute sulfuric acid.

### Step 1: Identify a Metal that Reacts Slowly with Dilute Sulfuric Acid
From the given list of metals in decreasing order of reactivity: Sodium, Calcium, Magnesium, Zinc, Iron, Lead, Copper, Gold, we need to find a metal that reacts slowly with dilute sulfuric acid.

- **Observation**: The metals at the top of the list (Sodium, Calcium, Magnesium, Zinc) are highly reactive and will react quickly with dilute sulfuric acid. As we move down the list, the reactivity decreases.
- **Conclusion**: Iron (Fe) is a metal that reacts slowly with dilute sulfuric acid compared to the metals above it in the reactivity series.
