Answer:
The answer to your question is letter A
Explanation:
Abundance Atomic mass
V-50 0.25% 49.947
V-51 99.750% 50.944
Formula
Average atomic mass = [V-50-Abundance x V-50-Atomic mass] +
[ V-51-Abundance x V-51-Atomic mass]
Substitution
Average atomic mass = [ 0.0025 x 49.947] + [0.9975 x 50.944]
= 0.125 + 50.817
Result
= 50.942 amu

E. Volume. hope this helps
Answer:
Option A and option D.
Explanation:
A. Kw = [H⁺] [OH⁻] / [H₂O] FALSE
This is the expression for the water's equilbirium.
2H₂O ⇄ H₃O⁺ + OH⁻
We can also say: H₂O ⇄ H⁺ + OH⁻
In the expression for K, we do not consider water.
Option C is correct: Kw = [H⁺] [OH⁻]
B. True
Kw = Ka . Kb
So, Ka = Kw / Kb
C. We saw, that is true.
D. Ka is not Kb⁻¹ . FALSE
Ka = Kw / Kb
Ka = 10^⁻(pKa)
Answer:
Higher temperature will cause more collisions.
Lower temperature will cause less collisions.
Higher temperature provides more activation energy!
