Answer:0.178 moles
Explanation: carbon trihydride seems to be an unusual name for the methyl group CH3–
ionic wt 15
moles = 2.67/15 = 0.178
It will appear to be the color red
Protons Ha and Hb in the compound given are enantiotopic.
<h3>What are enantiotopic protons?</h3>
Enantiotopic protons can be defined as those protons that can be replaced by another groups like deuterium.
<h3>What is a compound?</h3>
A compound is a substance which contains two or more elements chemically combined together.
So therefore, Protons Ha and Hb in the compound given are enantiotopic.

Answer:
W=-37.6kJ, therefore, work is done on the system.
Explanation:
Hello,
In this case, the first step is to compute the moles of each gas present in the given mixture, by using the total mixture weight the mass compositions and their molar masses:
Next, the total moles:
After that, since the process is isobaric, we can compute the work as:
Therefore, we need to compute both the initial and final volumes which are at 260 °C and 95 °C respectively for the same moles and pressure (isobaric closed system)
Thereby, the magnitude and direction of work turn out:
Thus, we conclude that since it is negative, work is done on the system (first law of thermodynamics).
Regards.
