Answer:
The differences in water temperature and salinity are responsible for deep water or ocean currents. Other inducing factors for water currents are wind, cabbeling, Coriolis effect and breaking waves.

Oceanic crust is more dense because it contains basalt which is more dense than granite which composes the continental crust.
Answer:
Number of moles = 0.0005 mol.
Explanation:
Given data:
pH = 3
Volume of solution = 500 mL
Number of moles = ?
Solution:
HCl dissociate to gives H⁺ and Cl⁻
HCl → H⁺ + Cl⁻
It is known that,
pH = -log [H⁺]
3 = -log [H⁺]
[H⁺] = 10⁻³ M
[H⁺] = 0.001 M
Number of moles of HCl:
Molarity = number of moles / Volume in litter
Number of moles = Molarity × Volume in litter
Number of moles = 0.001 mol/L × 0.5 L
Number of moles = 0.0005 mol
I just took a test with this question and got the answer wrong for saying ethane. The correct answer is propane.
