The heat lost is 
The heat lost when the ice is cooled from 400k to 263K can be calculated using the formula of heat transfer.
<h3>Heat Transfer</h3>
This is the heat transferred from a body of higher temperature to a body of lower temperature.
- Q = Heat Transfer
- m = mass = 1277g
- ΔT = change in temperature
We converted the temperature from kelvin scale into Celsius scale and find the change in temperature.
Solving for heat transfer
The heat loss is approximately

A. Scientific explanations are open to change.
Where temperature is constant P1V1 = P2V2 where P = pressure and V = volume.
so 1.25 * 2.5 = 95 * V2
V2 = (1.25 * 2.5) / 95
= 0.03 L to the nearest hundredth..

The reactant that will be the best reactant for a nucleophilic aromatic substitution is NO₂- NO₂. The correct option is b.
<h3>What is nucleophilic
aromatic substitution?</h3>
Nucleophilic aromatic substitution is a substitution process of nucleophile substance is substituted by halides in an aromatic ring. Aromatic compounds contain this type of substitution.
In option b, the compound is the one nitroxide group substituted by halogen, that is fluorine. The fluorine group is substituted in these given aromatic compounds.
Thus, the correct option is b, NO₂- NO₂.
