Which equation obeys the Law of Conservation of Mass?
A chemical equation shows you the actual "recipe" for a chemical reaction.
The left side of an equation is what you are starting with, it is called your reactants side.
The right side of an equation is what you are ending with, it is called your products side.The products side is what was produced as a result of the reaction
Which side of the equation below is the reactants side? Products side? Answer is below the equation.
CH4 + 2O2 ⟶CO2 +2H2O
The Law of Conservation of Mass says that mass cannot be created or destroyed in a chemical reaction.
In a chemical reaction, the mass of whatever you start with on the reactants side, must equal the mass that you end with on the products side.
When deciding if equations obey the Law of Conservation of Mass, you want to make sure that the same number of atoms of each element are on the reactants and products side.
Determine if the equations below obey the Law of Conservation of Mass.
