4K(s) + O2(g) --> 2K2O
The word equation for a candle burning in the air is: Wax + Oxygen → Carbon Dioxide + Water + Light + Heat.
Ca+O=CaO
Sodium particularly reacts with the Oxygen in the Air while burning. Sodium + Oxygen ----> Sodium oxide
The general equation for burning/combusting fossil fuels is:- fossil fuel + oxygen(air) = Carbon dioxide and Water.
18CO2 (g) +38HO2 (l)
For coal is carbon burning:C + O2 = CO2
ethanol + oxygen ----> Carbon Dioxide + water (assume complete combustion) CH3CH2OH + 3O2 ---> 2CO2 + 3H2O *also, when a compound is burning,we chemists use the term Combustion, which refers to the exothermic reactions which occur between some fuel source and an oxidant. Thus, "Ethanol burning in air" is rather redundant :]
Sulphur + air = sulphuric oxide
i have no idea mate
when cut, they are all shiny like gold, but then tarnish immediately
The word equation is magnesium + oxygen(air) = magnesium oxide. The Balanced chemical eq'n is 2Mg(s) + O2(g) = 2MgO(s)
C + O2 = CO2 That's a combustion (burning) reaction between carbon and oxygen molecules in air.
