CaCO3 -------> CaO + CO2
The word equation for a candle burning in the air is: Wax + Oxygen → Carbon Dioxide + Water + Light + Heat.
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Ch4 + 5o2 ------> co2 + 2h2o +302
A reaction of oxydation with the oxygen from air.
4Na + O2 ----> 2Na2O Sodium oxide is formed.

CaCO3 -------> CaO + CO2
2Cu(s)+O2(g) → 2CuO(s)
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O

When baking powder is used in baked products it produces carbon dioxide
It is when heated air rises quickly.
Sulphur + air = sulphuric oxide
i have no idea mate
