Consider the following chemical reaction. Molecular hydrogen and carbon dioxide react to form water and methane.

H2+CO2-->H2O+CH4

A)Explain why this equation is not balanced and what law of nature does it break in its current form?

B) Astronauts from the Earth carry large tanks of liquid hydrogen to Mars. During their 2 year stay on the red planet, how can they benefit from the above reaction? (PS:Martian atmosphere contains 96% carbon dioxide).


Please Help me I can't get the answer

  1. Not balanced because there isn't an equal amount of elements on either side of the equation (2 H on one side and 6 on the other etc.) It breaks the conservation of mass law.

    they would benefit because when hydrogen reacts with carbon dioxide it makes water, so the astronauts would have water.
