Question
Natural gas is a fuel that is used for heating and cooking in many homes and buildings. It is composed of almost pure methane, and burns with a hot, blue flame. The chemical equation for the burning of methane is shown below:
CH(4) + 20(2) -> CO(2) + 2H(2)O
Describe the burning of methane as a chemical reaction by explaining the following:
How can you tell from the chemical equation that this is a chemical reaction and not just a physical change? Tell me a fake answer
Is it an exothermic or endothermic reaction? What observations support your choice?
