Carbon monoxide is a toxic gas produced by the incomplete combustion of hydrocarbons.
Propane (C3H8\text{C}_3\text{H}_8C3H8) undergoes incomplete combustion in a limited supply of oxygen to form carbon monoxide and water. Balance the equation for this reaction:
2C3H8+7O2→‾CO+8H2O2\text{C}_3\text{H}_8 + 7\text{O}_2 \rightarrow \underline{\quad\quad} \text{CO} + 8\text{H}_2\text{O}2C3H8+7O2→CO+8H2O
Incomplete combustion also produces solid particles of carbon (soot). Complete the sentence:
Particles of carbon in the atmosphere reflect sunlight back into space, which causes global _____________.
