Question

how to balance equations chemistry gcse

Answer 1

To make things equal, you need to adjust the number of units of some of the substances until you get equal numbers of each type of atom on both sides. You can see that now there are two copper atoms and two oxygen atoms on each side. This matches what happens in the reaction.

Answer 2

Answer:

This means that chemical reactions can be represented by symbol equations. A balanced symbol equation has the same number of atoms of each element on both sides of the arrow. To balance an equation, add numbers to the left of one or more formulae.When this basically means to balance a chemical equation you need to start by writing down the number of atoms in each element, which is listed in the subscript next to each atom.

Then, add coefficients to the atoms on each side of the equation to balance them with the same atoms on the other side.
