Answer:
D. all of the above
Explanation:
A and C are verified by Keplar's laws of planetary motion.
B is verified by the equatorial and polar aces of the Planet.
A solution of a pH of 4 has 10 times the concentrations of H+ present compared to a solution with a pH of 5, where;
pH = - log [H+], the concentration of H+ of pH=4 is:
[H+] = anti Log (- pH) = 10 ^ - pH = 10 ^ - 4 = 0.0001 M >>>>> (1)
the concentration of H+ of pH = 5 is
10^ -5 = 0.00001 M >>>>> (2)
So, (1) more than (2) by 10 times
Hello!
Your answer is A.. Earth's core is the most dense layer and it consists of the outer core and the inner core.
Hope this helps :))
Answer:
As solution becomes acidic:
pH decreases in value
pOH increases also in value
[H1] concentration increases in value
[OH2] concentration decreases in value
As solution becomes basic:
pH increases in value
pOH decreases also in value
[H1] concentration decreases in value
[OH2] concentration increases in value
Explanation:
pH is the negative logarithm of the hydrogen ion concentration. Increase in acidity corresponds with decrease in pH value.
pOH is the negative logarithm of the hydroxyl ion concentration. Increase in basicity corresponds with increase in pOH value.
pH +pOH = 14
[H1] and [OH2] corresponds to the hydrogen and hydroxyl ion concentrations which increases with acidicity and basicity respectively.
