methane gas reacts with steam (water) to produce carbon monoxide gas and hydrogen gas.write the balanced formula equation for this reaction

Relevance

Methane is CH4

Water is H20

Carbon Monoxide is CO

Hydrogen Gas is H2

CH4 + H20 = CO + H2

That much you get from the word problem. Now you need to make sure you have enough molecules on each side. At the moment , you have enough C molecules (1 on each side). You have enough O molecules (1 on each side). But you have 6 H molecules on the left and only 2 on the right. This means the equation is not balanced. To balance it is quite easy - you will need 3 of the H2 on the right hand side. So just put a 3 in front of it and you're set.

So the equation is this:

CH4 + H20 = CO + 3H2

Methan is CH4

Water is H2O

Carbon Monoxide is CO

Hydrogen is H2

Therfore CH4 + H2O= CO+H2

This is not balanced, so balancing it makes;

CH4+H2O= CO+ 3x(H2)

All of the numbers,except the final '3', are subscript but i dont know how to do subsript in this window.
