Question

Write chemical equation for the following reactions. 

1. reaction of hydrogen with tungsten (VI) oxide NO₃ on heating. 

2. hydrogen gas and chlorine gas.

Answer 1

1. 3H₂ + WO₂ → W + 3H₂O 

Hydrogen reduces tungsten (VI) oxide. WO₃ to tungsten at high temperature. 

2. H₂ + Cl₂ → 2HCl (Hydrogen Chloride) 

Hydrogen reacts with chlorine at room temperature under light to give hydrogen chloride.
