Answer:
∆G = 35 KJ
Explanation:
The given data are as follows;
Gastric juice pH = 1.5
Blood plasma pH = 7.4
Temperature = (37 + 273) K = 310 K
However, pH = -log [H+]
Therefore, [H+] = 10^-pH
At pH of 1.5, [H+] = 10^-1.5 = 3.16 × 10^-2 M
At pH of 7.4, [H+] = 10^-7.4 = 3.98 × 10^-8 M
Using ∆G = RTln(C2/C1)
Where R = 8.314 J/mol/K;
T = 310 K;
C2 (concentration inside) = 3.16 × 10^-2 M;
C1 (concentration outside) = 3.98 × 10^-8 M
∆G = 8.314 × 310 × ln(3.16 × 10^-2 / 3.98 × 10^-8)
∆G = 35012.74
Therefore, ∆G = 35 KJ
Answer:
The correct answer is b) ethylmethylamine
Explanation:
This organic compound has the NH group (it is an amine), with 2 substitutions: a methyl group and an ethyl group.
Explanation:
The answer is 0.5 moles of gold
Chemical is the answer your looking for.
To convert from grams to moles, you divide the number of grams by the molar mass To convert from moles to grams, you multiply by the molar mass. You must first calculate the molar mass of the substance
