Answer:
True.
Step-by-step explanation:
A synthesis reaction is a type of chemical reaction in which two or more substances combine to form a new compound. Methane (CH4) and oxygen (O2) can combine in a synthesis reaction to form carbon dioxide (CO2) and water (H2O). This reaction is exothermic and is the basis of combustion reactions.
The balanced equation for this reaction is:
CH4 + 2O2 -> CO2 + 2H2O
In this reaction, one methane molecule and two oxygen molecules combine to form one carbon dioxide molecule and two water molecules.
It's worth mentioning that methane is considered a greenhouse gas, and the combustion of methane releases carbon dioxide and water vapor into the air, which contribute to global warming and climate change.
