Answer:
The crop failures were caused by late blight, a disease that destroys both the leaves and the edible roots, or tubers, of the potato plant.
The medium that might be used to cool the hot liquid coming from a reactor is : ( C ) Heat exchanger
<h3>Function of the heat exchanger</h3>
Heat exchanger is used for the transfer of heat between liquids to be used in a chemical reaction, It can be used for both Cooling and heating to achieve the desired temperature.
The liquid coming from a reactor which posses a very high temperature will be passed through the heat exchanger so that its temperature will attain the required temperature for the experiment.
Hence we can conclude that The medium that might be used to cool the hot liquid coming from a reactor is Heat exchanger.

Answer:
f. wt. = 158 g/mol
Explanation:
Given:
mass = 20.83 g
Vol = 4.167 L
Pressure = 79.97 KPa x 0300987 Atm/KPa = 0.78924 Atm
T = 30°C + 273 = 303K
R = 0.08206 L·Atm/mol·K
PV = nRT = (mass/f.wt.)RT => f. wt. = mass x R x T / P x V
f. wt. = 20.83g x 0.08206 L·Atm/mol·K x 303K / 0.78924 Atm x 4.167L
= 158 g/ mol
