Areaction requires water as a reactant and produces heat. what type of reaction is likely to be involved?

decomposition reaction

Explanation:

Chemical reaction is the process that involves the transformation of chemical elements or compounds into one, two or more products.

There are many types of chemical reaction and few are: combination reactions, displacement Reaction, reduction-oxidation Reaction, decomposition Reaction and so on.

But in this question; the Chemical Reaction involved is a decomposition reaction. Decomposition reaction is a chemical reaction that involves the breaking of one substance to simpler substances.

THINGS TO NOTE: (1). the reaction require water as a reactants. A popular reaction that requires water as a reactants is the electrolysis of water.

(2). The reaction produces heat. Normally, a decomposition Reaction is an endothermic reaction, but at some cases it changes to exothermic because of some conditions e.g the atmospheric condition.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
