Question

Hydrogen gas is evolved by reacting a piece of magnesium ribbon with water 1 Describe how it could be shown that the gas collected is hydrogen .
2 Write a chemical equation for the reaction taking place between magnesium and water using symbols

Answer 1

Answer:

1) when we take burning splinter near the gas, it burns with a pop up sound. so, therefore it shows that hydrogen gas is collected.

2) Mg + H2O - Mg(OH2) + H2

Hence, this the chemical equation.
