Question

a substance x,which is an of metal is used extensively in the cement industry.this element is present bone also.on treatment with also write the chemical reaction involved.

Answer 1

An oxide of group 2- oxygen
present in bones-calcium
X is CaO
chemical reaction involved-
CaO+ H2O - Ca(OH)2

Answer 2

Explanation:

Calcium is the metal that is indirectly used in cement. Calcium is present in our bones in the form of calcium oxide.

Chemical formula of calcium oxide is CaO. Therefore, substance X is calcium oxide.

The chemical reaction which involves calcium oxide is as follows.

   $CaO + H_{2}O \rightarrow Ca(OH)_{2}$
