D. container four because of the water
Well, I know one. A positive: decreasing pollution because most people are in quarantine and not outside.
Answer:
<h2>The answer is 34 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of aluminum = 91.8 g
density = 2.7 g/cm³
It's volume is
We have the final answer as
<h3>34 cm³</h3>
Hope this helps you
Answer:
Ketone
Explanation:
According to the description of the functional group attached to the hydrocarbon - the first and last of a chain of three carbons are each single bonded to 3 hydrogen (H)atoms; the center carbon is double bonded to an oxygen atom, O - it can be deduced that the functional group is a ketone group.
A ketone is a functional group with the structure R₂-C=O, where the two R are alkyl or phenyl groups which may be the same or different. The carbon in a double covalent bond with oxygen is called the carbonyl carbon. The two R groups are bonded to the carbonyl carbon in single covalent bonds.
In the hydrocarbon in this question, the two R groups are methyl groups, CH₃ bonded to the carbonyl carbon. The name of the hydrocarbon is propanone and it is a ketone molecule.
