Answer:
C
Explanation:
A - Crude oil is composed for hundreds of hydrocarbon, not less than ten.
B - Is formed in specific conditions of temperature and pressure
C - It's fractionated to form gasoline, lubricants, CH4, plastics and many other products made of hydrocarbon.
D - We have crude oil located more than 4000 yards below the surface in countries like Brazil
E - The crude oil is very thick and don't have an specific usage, so we need to refine it.
C.
D.
E.
These should be the main reasons. As Pluto was mainly categorized in dwarf planet for not being able to satisfy the last statement which states that it should have a fixed neighbourhood with other planets.
Lanthanide belongs to period 6, and actinides belongs to period 7
Answer:
[MgSO₄] = 890 mM/L
Explanation:
In order to determine molarity we need to determine the moles of solute that are in 1L of solution.
Solute: MgSO₄ (10.7 g)
Solvent: water
Solution: 100 mL as volume. (100 mL . 1L / 1000mL) = 0.1L
We convert the solute's mass to moles → 10.7 g / 120.36 g/mol = 0.089 moles
Molarity (mol/L) → 0.089 mol/0.1L = 0.89 M
In order to calculate M to mM/L, we make this conversion:
0.89 mol . 1000 mmoles/ 1 mol = 890 mmoles
