<u>Answer:</u> The speed of light in miles per minutes is 
<u>Explanation:</u>
We are given the speed of light is
and we need to convert it into miles/min. So, we use the converion factor:
1 hour = 60 minutes
Converting that quantity into miles/minutes, we get:

Hence, the speed of light in miles per minutes is 
Answer:
An alkyl halide can undergo SN2 reaction with an amine
Explanation:
The displacement of a bromine atom by an an amine (step 2---> 3) in the reaction sequence is an example of an SN2 reaction in which the amine is the nucleophile.
The nitrogen atom of the amine which bears a lone pair of electrons functions as the nucleophile and attacks the electrophilic carbon atom of the alkyl halide displacing the bromide and creating a new Carbon-Nitrogen bond. An ammonium intermediate is immediately formed and the reaction is completed by the abstraction of a hydrogen by a base (such as excess amine present in the system).
This reaction is slower with t-BuNH2 because of steric hindrance and steric crowding in the transition state. SN2 reactions are faster with methylamine where the alkyl carbon is easily accessible.
The detailed mechanism of this reaction has been attached to this answer.
The number of moles of the gas is 0.0396 moles.
<h3>What is the ideal gas equation?</h3>
The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.
Thus;
Volume = 1000.0 cm 3 or 1 L
Gas constant = 0.082 atmLK-1Mol-1
Temperature = 32 o C + 273 K = 305 K
Pressure = 752 mm Hg or 0.99 atm
Thus;
PV = nRT
n = PV/RT
n = 0.99 atm * 1 L/0.082 atmLK-1Mol-1 * 305 K
n = 0.0396 moles
