1. Metals react with acids to form a solution of a
and
gas is given off.
2. Complete the following word equations:
(a)
+
==> iron chloride + hydrogen
(b) zinc + sulphuric acid ==>
+
(c) calcium + hydrochloric acid ==>
+
(d)
+
==> magnesium sulphate + hydrogen
3. The following observations were made by a student when small quantities of the metals were added to dilute hydrochloric acid
| METAL | OBSERVATIONS |
| iron | slow bubbling |
| magnesium | lots of bubbles, heats up |
| copper | no bubbles at all? |
| zinc | quite rapid bubbling, maybe heated up? |
From these observations, work out the reactivity order
Most reactive:
:Least reactive
