Answer :
Final answer:
Combination reactions involve the transformation of multiple reactants into a single product, exemplified by the burning of methane. Combustion reactions, like burning fuels, are vigorous reactions that release heat and light, often involving oxygen. Combustion is a form of combination reaction where substances react with oxygen to create new products.
Explanation:
Combination reactions involve multiple reactants combining to form a single product. An example of a combination reaction is the burning of methane (natural gas) to produce carbon dioxide and water, releasing energy in the process.
Combustion reactions, such as the burning of fuels like coal or methane, are typically vigorous reactions accompanied by light and heat, often involving the reaction with oxygen.
In the context of the provided reactions, combustion is a key process where substances combine with oxygen to produce new products, making it a type of combination reaction.
