There won't be any change in the total mass of the atoms involved in a chemical reaction. According to the law of conservation of mass; it states that mass can neither be created nor destroyed in a chemical reaction. So, when atoms participate in a chemical reaction they might displace with other reactants but the total mass will remain the same.

Manipulating the left side of the equation, we obtain:
Using that
:
The formula is (new-original)/original.
(139,000 - 126,000)/126,000
= 13,000/126,000
= .103
Now, convert the decimal into a percent by moving the decimal two places to the right and including the percent sign.
.103 = 10.3%
Answer: 10.3%
First you have to do 27+35, which equals 62. Then you do x2, so 62x62= 3,844. The equation is x2= 27+35, x2= 3,844
