Each layer has a unique chemical composition, physical state, and can impact life on earths surface. Movement in the mantle caused by variations in heat from the core, causes the plates to shift, which can cause earthquakes and volcanic eruption‘s.
Answer:
At a greater value of pH, [H⁺] is really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.
Explanation:
pH = - log [H⁺]
10^-pH = [H⁺]
At pH = 8, [H⁺] = 10⁻⁸ → 1×10⁻⁸ M
At pH = 12, [H⁺] = 10⁻¹² → 1×10⁻¹² M
In conclussion, at a greater value of pH, [H⁺] will be really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.

The answer to your question is
51.- 1.59 x 10⁻⁶
53.- NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl
Explanation:
51.- Convert 0.00159 ml to liters
Use a rule of three
1000 ml -------------- 1 l
0.00159 ml --------- x
x = (0.00159 x 1) / 1000
x = 0.00000159 l = 1.59 x 10⁻⁶ l
53.- Sodium hydrogen carbonate (NaHCO₃) reacts with hydrochloric acid to produce salt, water and carbon dioxide.
Sodium hydrogen carbonate = NaHCO₃
Hydrochloric acid = HCl
Reaction
NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl
water = H₂O
carbon dioxide = CO₂
salt = NaCl
