Question

When mg is heated with steam it burns brilliantly producing?

Answer 1

Hydrogen gas and metal oxide

Answer 2

Answer: Magnesium oxide and hydrogen.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

$A+BC\rightarrow AC+B$

Thus as Mg is more reactive than hydrogen, then Mg can displace H from its solution to give Magnesium oxide and hydrogen.

The balanced chemical reaction will be:

$Mg+H_2O\rightarrow MgO+H_2$
