Answer:
The pH does not increase drastically because the NaOH reacts with the _HYDRAZOIC ACID__ present in the buffer solution.
Explanation:
NaOH reacts with the hydrazoic acid in the buffer
HN3 + OH? --> H2O + N3-
If you put acid in, it will react with N3-. Here is the equation below:
N3- + H+ --> HN3
Answer: Option (2) is the correct answer.
Explanation:
An element is defined as a substance that cannot be broken down into simpler substances.
For example, magnesium is a metal and it contains only atoms of magnesium.
Whereas a compound is defined as a substance that contains two different elements which are chemically combined together in a fixed ratio by mass.
For example, KCl is a compound in which atoms are present in 1:1 ratio.
Both an element and a compound are pure substances.
A mixture is defined as a substance in which two or more number of different substances are mixed together. Particles of a mixture never combine chemically to each other.
For example, cinnamon sugar is a mixture of different essential oils and spices.
Thus, we can conclude that the term mixture is the term which describes cinnamon sugar.
