C because, its products is heavier than each of its reactants
The pipette that accurately measures 0.8mL of fluid is P1000 micropipette.
It is given that:-
The volume of fluid = 0.8mL
We know that,
1 mL = 1000 microliter.
Hence,
0.8 mL = 0.8*1000 microliter = 800 microliter
We know that, a P1000 micropipette's volume ranges between 200 microliter to 1000 micro liter.
As,
200 < 800 < 100
Hence, P1000 micropipette is the right instrument.
The accuracy of this pipette decreases as volume decreases. Since the value 800 is near the maximum volume 1000 of the pipette, the accuracy of the pipette will be within a few percentages of the actual value.

The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
Answer:
Ether
SN1 mechanism
Explanation:
The nucleophile in this reaction is CH3OH. It is a poor nucleopile. We already know that a poor nucleophile reacting with a tertiary alkyl halide often leads to the substitution product as the major product.
Also, the iodide ion is a good leaving group. This makes the SN1 substitution more likely yielding the ether as the major product as shown in the image attached.
