How can you tell when an equation is balanced?

Answer 1

An equation is balanced if each atom on one side of the arrow has the exact same amount on the other side. You can balance the equation by adding coefficents in front of the element, but make sure there are the same amount. For example: if you have 3 atoms of Al on the left of the arrow, and 6 atoms of Al on the right side, all you have to do is add the number 2 as a coefficient in front of the first Al to make 6 atoms of Aluminum on each side.

Answer 2

To check if an equation is balanced, you should check if the number of atoms on both sides are equal or not. If they are not equal, balance them suitably. Next, check the charges on both sides. If charges are unequal, balance them too.

Answer 3

An equation is balanced when the number of atoms of each element on the left side of the equation is equal to the number of atoms of that element on the right side. This is achieved by adjusting the coefficients in front of each reactant and product to ensure that the equation obeys the law of conservation of mass.

Answer 4

When all amounts of elements are equal on both sides. i.e: 2H2O + Electricity --> 2H2 + O2.

2nacl+h2so4->hcl+naso4

Answer 5

Solve both sides...
