Answer:
All of these are true
Explanation:
A buffer solution in chemistry is a solution that resists changes in pH when an acid or base is added to it. It is a solution that contains a weak acid and its conjugate base (anion) or a weak base and its conjugate acid.
A buffer is able to resist a change in pH due to the conjugate base and conjugate acid of the weak acids and bases contained in them respectively. The conjugate base/acid are present in an equilibrium quantity with their acid/base counterparts and help to neutralize or react with any additional H+ or OH- from an acid or base added to their solution.
However, when a strong acid or base is added to the buffer solution, there is only a slight change which practically does not change the pH of the solution.
Hence, all of the above options about a buffered solution is true.
In order to use the energy stored in fat, the body breaks dow triglycerides into fatty acids, which individual cells burn for energy
When a certain compound is decomposed thermally, it means that the compound is separated into its individual pure elements occurring in nature. In this case, this happens in the presence of heat. The decomposition reaction is:
<span><em>4 NH</em></span><em>₄</em><span><em>ClO</em></span><em>₄</em><span><em> (s) --> 2 N</em></span><em>₂ (g)</em><span><em> + 5 O</em></span><em>₂ (g)</em><span><em> + 6 H</em></span><em>₂</em><span><em>O (g) + 4 HCl (g)</em></span>
