Step 1
Step 2
A student investigates the reactivity of four different metals.
Answer
For the observations of the metals:
- Magnesium: Bubbles produced at a steady rate, indicating the release of hydrogen gas, and may feel warm due to an exothermic reaction.
- Zinc: The test tube feels slightly warm, which suggests zinc is reacting but at a slower rate compared to magnesium since it is lower in reactivity.
- Iron: No observable reaction indicated.
- Copper: No reaction occurs as copper is less reactive than zinc and does not displace hydrogen from the acid.
