Im honestly not really sure ..
i just need points
im sorry
Answer: The molality of the CsCl solution is 3.2 m.
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
moles of solute =
Now put all the given values in the formula of molarity, we get
= weight of solvent (water) in g = 60.0 g
Molality =
Thus molality of the CsCl solution is 3.2 m.
Answer:D
Explanation:
The high boiling point of HF is not attributable to the dispersion forces mentioned in the question. In HF, a stronger attraction is in operation, that is hydrogen bonding. This ultimately accounts for the high boiling point and not solely the dispersion model as in F2.
Rock is a combination of two or more minerals, and it does not possess any specific chemical composition. It is present naturally in the environment. Some examples of rocks are limestone, granite, etc.,Limestone may contain minerals like calcite and aragonite. Each mineral has a specific chemical composition with a well defined crystalline structure.
Therefore, the correct option would be a. rock as rock is the naturally occurring solid mass made up of different types of minerals.
