What is the concentration of H^ + at apH = 2 ? Mol / L What is the concentration of H^ + ions at apH = 6 ? Mol/L How many more H^ + ions are there in a solution at a pH = 2 than in a solution at a pH = 6?

The concentration of hydrogen ion at pH is equal to 2 :

The concentration of hydrogen ion at pH is equal to 6 :

There are 0.009999 more moles of   ions in a solution at a pH = 2 than in a solution at a pH = 6.

Explanation:

The pH of the solution is the negative logarithm of hydrogen ion concentration in an aqueous solution.

The hydrogen ion concentration at pH is equal to 2 = [H^+]

The hydrogen ion concentration at pH is equal to 6 = [H^+]

Concentration of hydrogen ion at pH is equal to 2 =

Concentration of hydrogen ion at pH is equal to 6 =

The difference between hydrogen ion concentration at pH 2 and pH 6 :

Moles of hydrogen ion in 0.009999 mol/L solution :

There are 0.009999 more moles of   ions in a solution at a pH = 2 than in a solution at a pH = 6.

answer would be d.) i hope this

explanation:

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
