Question

Is the following nuclear equation balanced?


yes

no

Answer 1

For each spot, add the corresponding numbers on the left side and add the corresponding numbers on the right side. If they are equal for each spot, then the equation is balanced.

Here we have

234 -> 0 234 balanced because 234 = 0 + 234
90 -> -1 91 balanced because 90 = -1 + 91

so this equation is balanced.
