Ca + O = CaO.
zinc + oxygen ----> zinc oxide Symbol equation
2Cu+O2 ---> 2CUO
S+O2 = SO2
there isn't a proper symbol for it because it's nitrous plus oxygen the equation however is N2O 2 parts nitro 1 part oxygen
This equation is 2 CO + O2 -> 2 CO2.
S + o2 = so2
S (sulphur) + O2 (oxygen) = SO2 (sulphurdioxide)
Since graphite is basically Carbon C + O2 --> CO2
2Cu + O2 ---> 2CuOCopper + Oxygen ---> Copper II oxide
Word equation: ethanol + oxygen → ethanoic acid + water Symbol equation: C2H5OH + O2 → C2H4O2 + H2O
C3h8 + 5o2 -----> 3co2 + 4h2o
