Balance the following equation
1.Mg+O2--->MgO=
2.HgO--->Hg+O2=
3.Na+H2O--->NAOH+H2=
4.N2+H2--->NH3=
5.Fe+O2--->Fe+H20=
ctinamaria31:
the last one is wrong. u lost a H2

1.2Mg+O2--->2MgO=
2.2HgO--->2Hg+O2=
3.2Na+2H2O--->2NAOH+H2=
4.N2+3H2--->2NH3=
5.Fe+O2--->Fe+H20= WRONG 4 Fe + 3 O2 = 2 Fe2O3
2.2HgO--->2Hg+O2=
3.2Na+2H2O--->2NAOH+H2=
4.N2+3H2--->2NH3=
5.Fe+O2--->Fe+H20= WRONG 4 Fe + 3 O2 = 2 Fe2O3

1.2Mg + O2--->2MgO (magnesium oxide)
2.2HgO--->2Hg+O2
3.2Na+2H2O--->2NAOH(sodium hydroxide) +H2( hydrogen gas)
4.3N2+3H2--->2NH3 ( Ammonia )
5.Fe+O2--->Fe+H20 [ it is wrong equation]
it should be
4Fe+3O2⇒2 Fe2O3 (ferrous oxide)
2.2HgO--->2Hg+O2
3.2Na+2H2O--->2NAOH(sodium hydroxide) +H2( hydrogen gas)
4.3N2+3H2--->2NH3 ( Ammonia )
5.Fe+O2--->Fe+H20 [ it is wrong equation]
it should be
4Fe+3O2⇒2 Fe2O3 (ferrous oxide)
u forgot smth at the first one
2Mg in -> Mg out. it should be 2. the same fot oxygen
thanks
mark my answer best plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
