Question

c₂h₆o + o₂ → co₂ + h₂o
o decomposition
o combustion
o synthesis
o double replacement
o single replacement

Explanation:

Combustion reactions involve a substance reacting with oxygen (usually from the air) to produce carbon dioxide and water (if the reactant contains carbon and hydrogen). In this case, \(C_2H_6O\) (ethanol) reacts with \(O_2\) to form \(CO_2\) and \(H_2O\), which is characteristic of a combustion reaction. Decomposition reactions involve a single compound breaking down into simpler substances. Synthesis reactions involve combining simpler substances to form a more complex one. Single - replacement reactions involve one element replacing another in a compound. Double - replacement reactions involve the exchange of ions between two compounds.

Answer:

combustion
