Answer:
(B)
Explanation:
The colligative properties of any given solution are properties that are dependent on the concentration of the molecules or ions of the solute in the solution, and not on the type or identity of that solute. Examples of colligative properties:
1. Lowering of vapour pressure
2. Elevation of boiling point,
3. Depression of freezing point and
4. Osmotic pressure
(A) is not a colligative property because the scenario talks about the freezing point of a pure solvent and not a solution.
(C) is not a colligative property because the solutions being compared are completely different (the solutes are different).
(B) is a colligative property because it talks about the freezing point of a solution
Answer: Im not sure if you are doing this in your class.
Explanation:
So... for the element of MAGNESIUM, you already know that the atomic number tells you the number of electrons. That means there are 12 electrons in a magnesium atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and two more in shell three
Answer:
Mass = 0.000176 gram
Steps:
m = V × ρ
= 20 milliliter × 8.8 gram/cubic meter
= 2.0E-5 cubic meter × 8.8 gram/cubic meter
= 0.000176 gram
