Answer: Thus
is a secondary alkanol.
Explanation:
Alkanol are compounds which contains carbons bonded by single bonds and contains hydroxy (-OH) as functional group.
Primary alkanol are those compounds which contain hydroxyl group attached a carbon which is further attached to a single carbon atom. Example:
and 
Secondary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to two more carbon atoms.Example:
Tertiary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to three more carbon atoms. Example: 
Thus
is a secondary alkanol.
Answer:
The phase transition from a solid to a gas.
Explanation:
Entropy is related to the moles of gases available. The more gaseous moles, the higher the entropy.
<em>Identify the process in which the entropy increases.</em>
- <em>the phase transition from a solid to a gas</em>. YES. There are more gaseous moles available so entropy increases.
- <em>a decrease in the number of moles of a gas during a chemical reaction</em>. NO. This causes a decrease in entropy.
- <em>the phase transition from a liquid to a solid</em>. NO. There is almost no change in the entropy in this process.
- <em>the phase transition from a gas to a liquid</em>. NO. There is a decrease in entropy in this process.
- <em>the phase transition from a gas to a solid</em>. NO. There is a decrease in entropy in this process.
% m/v of the solution = 0.2%m/v

or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate
