Answer:
your welcome
Explanation:
The electronic configuration of chlorine can be written as 2, 8, 7. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.
Answer:
½N 2(g) + O 2(g) + 8.1 kcal → NO 2(g)
½N 2(g) + ½O 2(g) → NO(g), ΔH = +21.6 kcal/mole
NH 3(g) → ½N 2(g) + 3/2H 2(g), ΔH = +11.0 kcal/mole
General Formulas and Concepts:
<u>Thermochemistry</u>
- Endothermic vs Exothermic
- Enthalpy
Explanation:
An endothermic reaction would have heat or energy gained in the final stage of the reaction.
This means that our enthalpy would be positive and heat/energy would be added as a reactant.
Out of all the answer choices, we see that only these have heat/energy added in the reactant side or the enthalpy being positive:
½N 2(g) + O 2(g) + 8.1 kcal → NO 2(g)
½N 2(g) + ½O 2(g) → NO(g), ΔH = +21.6 kcal/mole
NH 3(g) → ½N 2(g) + 3/2H 2(g), ΔH = +11.0 kcal/mole

Answer:
bcs the oven heated it up?
Explanation:
Answer:
See attached picture.
Explanation:
Hello!
a) In this case, since oxygen there is present as C=O, as shown on the attached picture, we can see the following functional groups:
- Double bond (alkene).
- Amide group.
- Nitrile group.
b) In this case, since Et suggest an ethyl radical (CH3-CH2-) and the presence of those 2 oxygen atoms accounts for carboxyl, we have:
- Two carboxyl groups for an ethyl propanedioate ester.
Best regards!
