Answer:
Option D. Saturated alkane
Explanation:
To know which option is correct, it is important that we know what saturated and unsaturated compounds are in this context.
Saturated hydrocarbons are compounds which has only carbon to carbon single bonds (C–C) in its chain. A very good example of such compound is the Alkanes.
Unsaturated hydrocarbons are compounds which has either a carbon to carbon double bond (C=C) or a carbon to carbon triple bond (C≡C) in its chain. Examples of such compounds include alkenes and alkynes.
Now, let us answer the question given above bearing the meaning of saturated and unsaturated compounds in mind.
The compound given above contains only carbon to carbon (C–C) single bond.
Therefore, the compound is a saturated alkane.
I think that it is A) Conduction
Answer:

Explanation:
,
are strong electrolytes. Hence they are fully ionized in aqueous solution.
is a sparingly soluble salt. Hence it remains undissociated in aqueous solution.
So, total ionic equation:

Net ionic equation is written by omitting spectator ions from total ionic equation.
Here,
and
ions are spectator ions as they remain present on both side of total ionic equation.
So, net ionic equation:

So, option (d) is correct.
Food, Storage, and Structure
Negative enthalpy change and positive entropy change. I am sure that's the answer!
