Which of the following is a combustion reaction? a. h2 (g) + cl2 (g) → 2hcl (g) b. 2na (s) + cl2 (g) → 2nacl (s) c. c (s) + o2 (g) → co2 (g) d. caco3 (s) → cao (s) + o2 (g)

The answer is (C) as

→

It is commonly known that oxygen has the importance in the combustion reaction and in the absence of this molecule, the no combustion reaction will proceed. SO, for the combustion reaction, it is important that oxygen must be present in the reactant side of the equation than on the product side. Another identity is also present in the combustion reaction as carbon dioxide and water will be present in the product side. In the present options, the oxygen is only present in equation (C) in the reaction side.

So, the right option is

lol

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
