Question

Find the physical states of the substances and balance the chemical equations.

1) Co2+H2O ==> C6H12O6+O2

2) C3H8+O2 ==> Co2+H2O

3) Mg+O2 ==> MgO

4) C+Fe2O3 ==> Fe+Co2

Answer 1

1.)co2=gas;h2o=liquid;
6co2+6h2o=c6h12o6+6o2
2.)c3h8=liquid;o2=gas;
c3h8+502=3CO2+4H20
3.)Mg=solid;O2=gas;
2Mg+O2=2MgO
4.)C=gas;Fe2O3=solid;
3C+2Fe2O3=4Fe+3CO2
