Question

combustion reactions release ______. (1 point)

○ oxygen and water

○ light, carbon dioxide, and water

○ light and oxygen

○ oxygen and carbon dioxide

Explanation:

Combustion reactions are exothermic reactions that involve a fuel reacting with oxygen. For example, when a hydrocarbon (like methane, \(CH_4\)) undergoes combustion (\(CH_4 + 2O_2
ightarrow CO_2+2H_2O\)), heat and light are released as forms of energy. Also, carbon - containing fuels produce carbon dioxide (\(CO_2\)) and water (\(H_2O\)) as products. Oxygen is a reactant in combustion, not a product. So, combustion reactions release light (as a form of energy), carbon dioxide, and water.

Answer:

light, carbon dioxide, and water
