For a neutralization reaction, the value of q(heat of neutralization) is doubled when the concentration of only the acid is doubled.
A neutralization reaction is a reaction in which an acid reacts with a base to yield salt and water. Ionically, a neutralization reaction goes as follows; H^+(aq) + OH^-(aq) ------> H20(l).
The heat of neutralization (Q) of the system depends on the concentration of the solutions. Since Q is dependent on concentration, if the concentration of any of the reactants is doubled, more heat is evolved hence Q is doubled.

<h3><u>Answer;</u></h3>
Adaptation
<h3><u>Explanation;</u></h3>
- Adaptation refers to the process in which animal or plant species becomes fitted to the environment. This occurs as a result of genetic changes or mutations.
- Adaptations may be, behavioral, psychological or structural. Behavioral adaptations are responses made by an organism which help it to survive.
- Psychological adaptations are body processes that helps and organism to survive or reproduce, while structural adaptations are features of the body of organisms which helps it survive or reproduce.
Half-life is defined
as the time which is taken to reduce the initial amount of isotopes by half.
Hence, after one half-life,
half of initial amount of isotopes will remain.
