#"Garbage in equals garbage out....."#

Explanation:

Every chemical process conserves MASS and CHARGE absolutely. If the given equation does not reflect this mass balance, then it cannot be accepted as a manifestation of reality.

Is this balanced....

#CH_4 + O_2 rarr CO_2 + H_2O#

Are mass and charge conserved?

What about for....

#underbrace(CH_4+2O_2)_"80 g" rarr underbrace(CO_2 + 2H_2O)_"80 g"#
