Answer

Answer:

  1. B. 1, 3, 2, 4

Explanation:

Step1: Analyze burning octane fuel

Burning octane is a combustion reaction and occurs very rapidly as it releases a large amount of energy quickly.

Step2: Analyze baking a cake

Baking a cake involves multiple chemical reactions like the decomposition of baking - soda and reactions between ingredients, but it is slower than combustion.

Step3: Analyze forming rust in an iron pipe

Rusting of iron is an oxidation reaction that occurs over a relatively long period of time as it involves the slow reaction of iron with oxygen and water.

Step4: Analyze cement hardening

Cement hardening is a very slow process that can take days to weeks as it involves the hydration of cement compounds and the formation of a solid structure. So the order from fastest to slowest is burning octane fuel (1), baking a cake (3), forming rust in an iron pipe (2), cement hardening (4).
