Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
Oxidation
The equation given is correctly balanced, because it contains the same numbers of each kind of atoms in the reactants as in the products.
A quadratic equation.
That's the equation.
That word "equals" in there makes it an equation.
2H2 + O2 --> 2H2O
This is a balanced chemical equation.
Zn + CuSO4 -> ZnSO4 + Cu
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
its already balanced
iron :)
2Al + N2 ----> 2AlN
2
No. It would have to be H2O2 - H2 = O2 in order to be balanced.

Because on one side you have two hydrogens and two oxygens and on the other side of the equation you have two hydrogens and only one oxygen.
Me too i don't know
