Answer 1

Answer:

Oi, What have u written. First of all If Hydrogen mixes with CO2 how can water form? The thing that's formed is H2CO3.

Answer 2

ANSWER:

When hydrogen gas burns in the air, it combines with Carbon dioxide, and water is formed.

The equation is as follows:

CO2 + 4 H2 --------> CH4 + 2H20

(under 3MPa pressure

Temperature 300°c

nickel as catalyst agent)

This reaction is known as SABATIER REACTION.

• under atmospheric pressure Hydrogen gas reacts with oxygen to form vapors of H20
• The Sabatier reaction is a type of methanation of CO2.
• Sabatier relation is used for the synthesis of natural gas
• It is also used for the manufacture of ammonia.
• The methanation process is used for the removal of exhaled CO2 by the astronauts in space. Hence it is used in international space station life support.
