Step 1
Step 2
A student investigates the reactivity of four different metals.
Answer
Based on the observations:
-
Magnesium: When magnesium is added to dilute hydrochloric acid, a vigorous reaction occurs, producing hydrogen gas and magnesium chloride. This can be noted as it produces bubbles rapidly.
-
Zinc: The observation indicates that zinc produces bubbles at a steady rate and the test tube feels slightly warm, suggesting a moderate reaction that releases hydrogen and generates heat.
-
Iron: The observation for iron is not provided, though typically it reacts slowly with dilute hydrochloric acid.
-
Copper: The absence of any reaction with copper is indicated by 'no reaction'. Copper is less reactive and does not displace hydrogen from the acid.
