Answer:

The description for the given question is described in the explanation section below.

Explanation:

Combustion reaction is given below,

C₂H₅OH(l) + 3O₂(g) ⇒ 2CO₂(g) + 3H₂O(g)

Provided that such a combustion has a normal enthalpy,

ΔH°rxn = -1270 kJ/mol

That would be 1 mol reacting to release of ethanol,

⇒ -1270 kJ of heat

Now,

0.383 Ethanol mol responds to release or unlock,

=0.383 \ mol\times -1270 \ kJ/mol

=-486 \ kJ

jeka57 [31]
You can start with:

"Dear Representative Name Here:

As a student, I am interested in how you are involved within the government. I wish to inquire about the committees that you currently served in, whether it is state or local. It will be very useful for me to study someone with a local perspective.

I also wish to find out about what types of bills you have submitted. These bills may pertinent towards my own studies, especially if they involve any of the local issues.

I would furthermore request that you enclose in your reply a copy of a speech that you have made in Congress. It is good to learn from your stances directly.

Thank you for your consideration.

Sincerely,

Your Name"

There's not enough rhetoric but this is a start.
