Answer: The given reaction is a neutralization reaction.
Explanation:
When an acid chemically reacts with a base then it leads to the formation of salt and water.
For example, 
Here, KOH is a the base and
is an acid which on chemical reaction with each other leads to the formation of salt
and water
.
Thus, we can conclude that the given reaction is a neutralization reaction.
Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.
<h3>What is an Exothermic Reaction ?</h3>
When a chemical reaction happens, energy is transferred to or from the surroundings.
When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.
ΔH value negative –> energy released –> exothermic reaction
This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.
The energy diagram for the exothermic reaction is attached with this answer.

The reason why the sky is blue is because it is reflecting off of the sky and when it is evening its losing light
Answer:
V₂ = 16.5 L
Explanation:
To solve this problem we use <em>Avogadro's law, </em>which applies when temperature and pressure remain constant:
V₁/n₁ = V₂/n₂
In this case, V₁ is 22.0 L, n₁ is [mol CO + mol NO], V₂ is our unknown, and n₂ is [mol CO₂ + mol N₂].
- n₁ = mol CO + mol NO = 0.1900 + 0.1900 = 0.3800 mol
<em>We use the reaction to calculate n₂</em>:
2CO(g) + 2NO(g) → 2CO₂(g) + N₂(g)
0.1900 mol CO *
0.1900 mol CO₂
0.1900 mol NO *
0.095 mol N₂
- n₂ = mol CO₂ + mol N₂ = 0.1900 + 0.095 = 0.2850 mol
Calculating V₂:
22.0 L / 0.3800 mol = V₂ / 0.2850 mol
V₂ = 16.5 L
