Question

which describes one of oxygens roles in earths atmosphere? allows fuels to burn forms clouds that produce rain is the gas that animals exhale is used by plants to produce food

Explanation:

• Oxygen is a highly reactive gas. In combustion (burning) reactions, oxygen acts as an oxidizing agent. For example, in the reaction \(C + O_2

ightarrow CO_2\) (carbon burning in oxygen), oxygen helps in the process of burning.

• Clouds that produce rain are mainly formed from water vapor (\(H_2O\)), not oxygen (\(O_2\)).
• Animals exhale carbon dioxide (\(CO_2\)), not oxygen.
• Plants use carbon dioxide (\(CO_2\)) and sunlight to produce food (glucose) through photosynthesis (\(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\)), not oxygen.

Answer:

allows fuels to burn
