A student investigates the reactivity of four different metals with dilute hydrochloric acid.
The student adds an equal-sized sample of each metal to separate test tubes containing the same volume and concentration of dilute hydrochloric acid.
Some of the student's observations are recorded in the table below:
| Metal | Observations |
|---|---|
| Calcium | Very vigorous reaction, extremely rapid production of bubbles, test tube becomes hot |
| Magnesium | |
| Nickel | Slow production of bubbles, test tube feels slightly warm |
| Silver |
Use the reactivity series diagram and the table of observations to predict the results for the reactions of magnesium and of silver with dilute hydrochloric acid.
