Answer:
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:
3675 J
Explanation:
Gravitational Potential Energy = × mass × g × height
( g is the gravitation field strength )
Mass = 50 kg
G = 9.8 N/kg ( this is always the same )
Height = 15 m
Gravitational Potential Energy = × 50 ×9.8 × 15
= 3675 J
