What is a balanced equation in science?

Answer 1

a balanced equation is when all matter is accounted for on both sides. This is important because matter cannot be created or destroyed. For example, the creation of glucose through photosynthesis looks like this:

CO2 + H2O = C6H12O6 + O2 + H2O

This is an unbalanced equation because there is not enough oxygen, hydrogen, and carbon on the left side to create the right side. The balanced equation would be:

6 CO2 + 12 H2O = C6H12O6 + 6 O2 + 6 H2O

The number of oxygen, hydrogen, and carbon atoms on each side, when subtracted, create 0 which means all matter is accounted for and therefore the equation is balanced

Answer 2

A balanced equation in science is a chemical equation where the number of atoms of each element is the same on both sides of the equation. This ensures that mass is conserved during a chemical reaction. Balancing an equation involves adjusting the coefficients in front of the chemical formulas to achieve this balance.
