Answer:
Explanation:
MM: 30.01
N₂ + O₂ ⟶ 2NO; ΔH = +43 kcal/mol
m/g: 147
Treat the heat as if it were a reactant in the reaction. Then you can write
N₂ + O₂ + 43 kcal ⟶ 2NO
The conversion factor is then 43 kcal/2 mol NO.
1. Moles of NO
2. Amount of heat
Answer:
The net charge on each lysine molecule would be -1.
Explanation:
- <u>When the pH is above 2.2</u> the deprotonated form of the carboxylic acid is more present, while the amino group and side chain (which is also amino) remain protonated (with a positive charge):
R-COOH ↔ R-COO⁻
R-NH₃⁺
R'-NH₃⁺
Net charge = +1
- <u>When pH is above 9.0</u>, the carboxyl group remains deprotonated, while the amino group is deprotonated and the side chain is protonated:
R-COOH ↔ R-COO⁻
R-NH₂
R'-NH₃⁺
Net charge = 0
- <u>When pH is above 10.5</u>, the carboxyl group remains deprotonated, while both the amino group and the side chain are deprotonated:
R-COOH ↔ R-COO⁻
R-NH₂
R'-NH₂
Net charge = -1
So at pH=13 (which is above 10.5) the net charge is -1.
It would be:
2H2 + O2 -> 2H2O
Answer:
Exosphere
Explanation:
it’s the furthest away from the earths surfest which would make it furthest away from earths center.
