Balance the following equations:

a. C + O2 CO
b. CO + O2 CO2
c. H2 + Br2 HBr
d. K + H2O KOH + H2
e. Mg + O2 MgO

• Genera Chemistry -

I will do two:

CO + O2>> CO2
2CO+O2>> 2CO2

K+ H2O>> KOH + H2
I find it helpful to write H2O as HOH
K+HOH>>KOH + H2
2K + 2HOH>> 2KOH + H2

then rewrite HOH as H2O
