1. Metal carbonates react with acids to form a
, water and the gas
.
2. The gas given off in the reaction can be tested for with
which is turned
.
3. When the
powder
carbonate is dissolved in sulfuric acid a
solution of the salt copper
is formed.
4. Complete (a sort of balance!) the set of
:
5a.
carbonate + hydrochloric acid ==> calcium
+
+ carbon dioxide
5b.
carbonate + nitric acid ==> zinc
+ water +
5c. magnesium
+ sulfuric acid ==>
sulfate + water + carbon dioxide
