Answer: C. a compound in which one or more carbon atoms have double or triple bonds.
Explanation:
Saturated hydrocarbons are defined as the hydrocarbons in which single bond is present between C-C atoms. The general formula used for these hydrocarbons is . Example:
Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent bonds present between carbon and carbon atoms. They are known as alkenes and alkynes respectively. The general formula used for these hydrocarbons is and
respectively. Example:
Both the hydrocarbons are not soluble in water as they are non polar in nature unlike water which is polar.
Cycloalkanes are also saturated hydrocarbons as single bond is present between C-C atoms.
Thus the correct statement is An unsaturated hydrocarbon is a compound in which one or more carbon atoms have double or triple bonds.
Answer:
15 mL of 15% acid solution and 30 mL of 3% acid solution
Explanation:
The total number of moles of the mixture is equivalent to the addition of the number of moles of the first solution
and the number of moles of the second solution
. Mathematically,
The volume of the mixture = 45 mL
The volume of first solution = x
The volume of second solution = 45 - x
Therefore:
0.15x + 0.03(45-x) = 0.07*45
0.15x + 1.35-0.03x = 3.15
0.12x = 1.8
x = 15
Thus, the volume of the first solution is 15 mL while the volume of the second solution is 30 mL.
