Write the reaction equations for the combustion of aluminum, sulfur, copper, propane C3H8.

Write the reaction equations for the combustion of aluminum, sulfur, copper, propane C3H8. Sign the names of the reaction products.

Let’s write down the combustion reactions:
4Al + 3O2 = 2Al2O3 – combustion is accompanied by bright flashes, aluminum oxide is obtained;
S + O2 = SO2 – sulfur burns with a bright blue flame, sulfur oxide is released (4);
Cu + O2 = 2CuO – blue flame, copper oxide obtained (2);
С3Н8 + 5О2 = 3СО2 + 4Н2О – propane combustion;
The combustion reactions of metals are redox reactions, while the metal exhibits the properties of a reducing agent, oxygen is an oxidizing agent. Propane is used as fuel, the reaction is exothermic.
