which type of chemical reaction occurs in c6h12 + 9o2 → 6co2 + 6h2o?\nsynthesis\ncombustion\nsingle…

Brief Explanations:

Combustion reactions involve a substance reacting with oxygen to produce carbon - dioxide and water (among other products). Here, C6H12 reacts with O2 to form CO2 and H2O, which is characteristic of a combustion reaction. Synthesis reactions combine 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:

B. combustion
