which of the following equations demonstrates the law of conservation mass
a. CH4 + O2 -> CO2 + HO
B. CH4 + O2 -> CO2 + H2O
C CH + O2 -> CO2 + H2O
D CH4 + O2 -> C + 2H2O
1 answer
The equation that demonstrates the law of conservation of mass is B. CH4 + O2 -> CO2 + H2O. This is because the number and types of atoms (carbon, hydrogen, and oxygen) on both sides of the equation are equal, indicating that mass is conserved in the reaction.
