You can explain what it means...like how gas tends to expand when heated and just tie it up with the sentence you want to make....(i dont know if that was helpful?)
The ammonium iodide solution is converted into a buffer by the addition of ammonia (NH₃).
<h3>What is a buffer solution?</h3>
- A solution which is formed by the addition of weak acid and its conjugate base or weak base and its conjugate acid.
- They resist a change in pH of the solution when an acid or alkali added to them.
<h3>Which is to be added to the given solution to convert it into a buffer?</h3>
The given solution contains 0.21 M ammonium iodide (NH₄I). This is a salt of a weak base(NH₃) and a strong acid(HI).
NH₄I(s) → NH₃(g) + HI(g)
Where the salt is ionic. So, in aqueous solution it dissociates into NH₄⁺ and I⁻
The ammonium ion NH₄⁺ is the conjugate acid of the weak base NH₃.
So, the mixture of this weak base NH₃ and its conjugate acid NH₄⁺ converts the solution into a buffer.
Therefore, one liter of the given solution could be converted into a buffer by the addition of a weak base NH₃.

Answer;
Ge and As.
Explanation;
Elements Ge and As belong in the same period as krypton.
Each row of the periodic table is called the period.
Elements in each period have the same number of electron shells.
These elements in the same period do not have similar properties- the properties change greatly across every period. Krypton is in period four therefore all the elements in period 4 have four electrons shells.
the answer is c, more heat is being released.
