For each chemical equation, list the number of each type of atom on each side of the equation, and determine if the equation is balanced.?

List the number of each type of atom on the left side of the equation

MgS(aq)+2CuCl2(aq)→2CuS(s)+MgCl2(aq)

List the number of each type of atom on the right side of the equation

MgS(aq)+2CuCl2(aq)→2CuS(s)+MgCl2(aq)

List the number of each type of atom on the left side of the equation

2C10H22(l)+31O2(g)→20CO2(g)+22H2O(g)

List the number of each type of atom on the right side of the equation

2C10H22(l)+31O2(g)→20CO2(g)+22H2O(g)

    This is a very simple matter. Just count each type of atom on each side of the equation. If they are not the same, the equation is not balanced.

    MgS(aq)+2CuCl2(aq)→2CuS(s)+MgCl2(aq)

    Mg: 1 and 1

    S: 1 and 2

    Cu: 2 and 2

    Cl: 4 and 2

    The equation is not balanced

    You should be able to do the rest of these on your own.
