Question

With all the coefficient set to 1, how can you tell that the equation is not balanced?

Answer 1

Well for any equation if all the coefficients are set to 1, this might result in unequal numbers of atoms of the same element on both sides

Step-by-step explanation:

For example:

`A+B---->B_(2) + A_(2)` (for this equation all the coefficient (the number before element) are 1 but you can clearly see it is not balanced because one side has 1 A atom and other side has 2 B atoms....therefore we need to balance em.

`2A+2B-----> A_(2) + B_(2)` Here both atoms are balanced.
