Question

write chemical equation for the reaction taking place when a)Iron reacts with steam. b) magnesium reacts with dilute HCl. c) copper is heated in air (oxygen)​

Answer 1

Explanation:

The reactions are as follows:

Mg+HCl= MgCl2+H2

Fe+H2O=Fe2O3 + H2

Cu+O2= CuO

Explanation:

Magnesium reacts with dilute hydrochloric acid to form Magnesium dichloride and hydrogen gas. Iron reacts with water vapours to form iron (III) oxide.

It is one of the three oxides of iron. It is often called as rust. It corrodes the metal and makes it weak. Copper reacts with oxygen to form Copper oxide. It is semi-conducting material and possesses a range of properties such as superconducting.

Answer 2

Answer:

a). 2 fe + 3 H2O ----Fe2O3 + 3H2O

b.) Mg + 2 HCl ---. MgCl2 + H2

c.). 2Cu + O2 --- 2CuO
