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

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
