Answer:
None of carbonyl group is attached to hydrogen atoms.
Explanation:
Ketone is a group in which one carbonyl group is attached to two R ( the alkyl group) .
And the group in which two hydrogen is attached to R is called as aldehyde (formaldehyde).
And when one hydrogen and one alkyl group is attached to R. It is called as acetaldehyde from aldehyde family.

Complete Question
A sample of aluminum, which has a specific heat capacity of 0.897 JB loc ! is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The aluminum sample starts off at 85.6 °C and the temperature of the water starts off at 16.0 °C. When the temperature of the water stops changing it's 20.1 °C. The pressure remains constant at 1 atm. Calculate the mass of the aluminum sample.
Answer:

Explanation:
From the question we are told that:
Heat Capacity 
Mass of water 
Initial Temperature of Aluminium 
Initial Temperature of Water 
Final Temperature of Water 
Generally
Heat loss=Heat Gain
Therefore


These substances can be separated by distillation, so your answer is A.
