Answer:
- What distinguish a solution in general from an aqueous solution is the solvent. A solution in general may contain any solvent, which may be solid, liquid or gas, while an aqueous solution is formed with water as solvent.
Explanation:
A solution in general is a homogeneous mixture in which a substance, named solute, is dissolved, in other substance, name solvent.
Solutions may be in solid, liquid or gas state. There are many kind of solvents. Usually, in a lab you work with liquid solutions. Some liquid solvents are: ethanol, glycerin, hexane, benzene, and water, among many others.
Aqueous solution is a solution where the solvent is water. Of course, the solute may be any one: NaCl, sugar, ethanol, an acid, a base, a salt.
What distinguish a solution in general and an aqueous solution is the solvent.

Answer:
The average number is given as 48.6
Explanation:
From the question we see that the
Percentage of cis = 47.2%
Percentage of trans = 44.9%
Percentage of vinyl = 7.9%
The chemical reaction equation for the hydrogenation of polybutadiene is shown on the first uploaded image
To obtain the average number of backbone carbon between the ethyl side chains ,we divide the total number of carbon on the backbone by the total number of ethyl group
That is
= (44.9% × 4 + 47.2% ×4 + 7.9% × 2) ÷(7.9% × 1)
= (384.2%/7.7%)
= 48.6
Note : The percentage will cancel out
