What type of chemical reaction is given by the following balanced equation: 2c8h18 + 25o2 → 16co2 + 18h2o a) synthesis b) combustion c) decomposition d) double replacement

B - Combustion

This is because combustion always produces the products of water and carbon dioxide.

Synthesis is incorrect as the two reactants didn't necessarily synthesize. Decomposotion is incorrect as the reactants also didn't entirely decompose. Double replacement is incorrect as oxygen had been distributed between the other reactant.

Hope this helps!
