In two or more complete sentences explain how to balance the chemical equation, CH, + O2 → CO2 + H2O and include all steps.

CH4+2O2 -> CO2+2H2O

Explanation:

CH4+O2

C=1

H=4

O=2

CO2+H2O

C=1

O=2

H=2

O=1

(Total O=2+1=3)

To balance = make them have the same amount of atom both sides.

For C - Don't change anything coz they both have the same amount of atom.

For H - Makes H of the product side (right side) to 4 coz the left side has 4. Put 2 infront of H (right side) 2H2 = 4 atoms of H (2 infront of H x 2 after H)

For O - Now O (product side <right side>) will be come 2 coz we put 2 infront of H (they also x 2 to O as well).

So 2 ( the O before + (CO2) ) PLUS 2 after +.

So O in the product side has 4 atoms.

Now we have to makes reactant side to 4 atoms, put 2 infront of O (left side) =O2 >2O2
