Answer:
∆H= <u>438 KJ/mol</u>
Explanation:
First, we have to find the <u>energy bond values</u> for each compound:
-) Cl-Cl = 243 KJ/mol
-) F-F = 159 KJ/mol
-) F-Cl = 193 KJ/mol
If we check the reaction we can calculate the <u>number of bonds</u>:
In total we will have:
-) Cl-Cl = 1
-) F-F = 3
-) F-Cl = 6
With this in mind. we can calculate the <u>total energy for each bond</u>:
-) Cl-Cl = (1*243 KJ/mol) = 243 KJ/mol
-) F-F = (3*159 KJ/mol) = 477 KJ/mol
-) F-Cl = (6*193 KJ/mol) = 1158 KJ/mol
Now, we can calculate the total energy of the <u>products</u> and the <u>reagents</u>:
Reagents = 243 KJ/mol + 477 KJ/mol = 720 KJ/mol
Products = 1158 KJ/mol
Finally, to calculate the total enthalpy change we have to do a <u>subtraction</u> between products and reagents:
∆H= 1158 KJ/mol-720 KJ/mol = <u>438 KJ/mol</u>

Double bonds are not formed by chlorine. To complete its octet, oxygen requires two bonds (two single bonds or one double bond) and two lone pairs.
Chlorine can only form single bonds unless, for instance, it is bonded to oxygen (ClO3H), in which case, the oxygen forces chlorine to form double bonds.
The chemical element chlorine has the atomic number 17 and the symbol Cl. The second-lightest halogen, fluorine is situated between bromine and fluorine in the periodic table and has most of its features in the middle. At room temperature, chlorine is a gas that is yellow-green.

Answer is gas for sure and I think it’s ice for question 2
The answer is (4). The same magnitude and the opposite sign. For a proton, it has one positive electric charge. And for electron, it has one negative electric charge. So they have same magnitude but opposite sign.
Answer:
The correct answer is the final pair: C4H10 and C2H5
