Question

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

Answer 1

Favorite Answer

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

Answer 2

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.
