Which equation represents a combustion reaction? pb(no3)2 + 2hcl → pbcl2 + 2hno3 2so2 + o2 → 2so3 2c2h6 + 7o2 → 4co2 + 6h2o ca + 2hcl → cacl2 + h2

2C2H6 + 7O2 → 4CO2 + 6H2O

Explanation:

Combustion is when a hydrocarbon (a compound made of only hydrogen and carbon) reacts with oxygen at high temperature to produce CO2 and H2O gases.

it is a combustion reaction.

Explanation:

Combustion reaction is the type of reaction in which a hydrocarbon heated up in the presence of oxygen to form water and carbon dioxide.

is ethane and it is a hydrocarbon. The combustion reaction of ethane is as follows :
