    Yes

    1. If you mean MgBr2

    MgO+2HBr----->MgBr2+H2O

    2. 2N2+5O2---->2N2O5

    3. C2H4+3O2---->2CO2+2H2O

    4. Fe+2HCl----->FeCl2+H2

    well equation number one has Mg and Hg, which is it?

    2) balance the Oxygen first, you'll need 10 on each side then balance 3) the N

    4) balance the O2 last

    5) easy

    1)WRONG question

    2)

    3)C2H4+3O2=2CO2+2H2O

    4)Fe+2HCL=FECL2+H2
