which of the following is an example of a combustion reaction?

a. photosynthesis in plants
b. cellular respiration in humans
c. mixing of vinegar and baking soda
d. release of carbon dioxide on heating limestone

I am almost positive that the answer is D

Answer : The correct option is, (B) Cellular respiration in humans

Explanation :

Combustion reaction : It is defined as the hydrocarbon react with the oxygen then it react to give carbon dioxide and water as a product.

A. Photosynthesis in plants

Photosynthesis : It is a chemical process or a reaction which takes place in the green plants or the living organisms.

During this process, the carbon dioxide reacts with the water in the presence of sunlight to gives glucose and oxygen as a product.  

The balanced chemical reaction will be,

B. Cellular respiration in humans

Cellular respiration : In this process, the hydrocarbon react with the oxygen to give carbon dioxide and water as a product. This reaction is a combustion reaction.

Cellular respiration is directly opposite of photosynthesis.

The balanced chemical reaction will be,

C. Mixing of vinegar and baking soda

When vinegar is react with baking soda then it gives sodium acetate, carbon dioxide and water as a product. This reaction is an acid-base reaction.

The balanced chemical reaction will be,

D. Release of carbon dioxide on heating limestone

When limestone (calcium carbonate) is heated then it decomposes to give calcium oxide and carbon dioxide as a product. This reaction is a decomposition reaction.

The balanced chemical reaction will be,

Hence, from this we conclude that the example of combustion reaction is, (B) Cellular respiration in humans

the dissolution of polymer can be thermodynamically described in 2 steps.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
