Best ResponseYou've already chosen the best response.1Review this chemical equation: O2 + CH4 yields CO2 + H2O Which answer best explains what must be done to make this equation comply with the law of conservation of mass? (1 point) You must add a coefficient of 2 to the oxygen molecule on the left and a coefficient of 2 to the water molecule on the right. You must add a coefficient of 2 to the methane (CH4) molecule on the left and a coefficient of 2 to the carbon molecule on the right. You must add a coefficient of 4 to the oxygen molecule on the left and a coefficient of 4 to the water molecule on the right. You must add a coefficient of 2 to the oxygen molecule on the left and nothing to the molecules on the right.
