The image of the structure is attached in the image below.
<u>Answer: </u>The correct option is a.) 4-methyl-3-phenyl-3-pentenoic acid
<u>Explanation:</u>
Carboxylic acids are a type of functional group in organic chemistry that have the symbol '-COOH'. A suffix used for this functional group is '-oic acid'.
To name a compound, first look for the longest possible carbon chain.
As in the image attached below, the longest carbon chain has 5 carbon atoms. Thus, the prefix used will be 'pent-'
Also, a methyl substituent is present at the 4th position, a phenyl substituent is located at the 3rd position.
A double bond is also present at the 3rd position and a suffix '-ene' is used.
Hence, the IUPAC name for the given compound is 4-methyl-3-phenyl-3-pentenoic acid.

Answer:
3557J is the heat lost by the water
Explanation:
Using the equation:
Q = m*C*ΔT
<em>Where Q is change in heat</em>
<em>m is mass of substance (23g of water)</em>
<em>C is specific heat of the substance (4.18J/g°C)</em>
<em>And ΔT is change in temperature (68.0°C - 31.0°C = 37.0°C)</em>
<em />
we can find the amount of heat lost as follows:
Q = 23g*4.18J/g°C*37°C
Q =
3557J is the heat lost by the water
<em />
It is actually Group 3A elements. I just took the test.
