Answer:(9x) x 6 + (8x) x= the cost to take care of one member for one day
Explanation:
the receipt takes care of one of the members for one day which is the "+ (8x)" there is no number to represent the cost, so this is all that's possible
Answer is: adding NaCl will lower the freezing point of a solution.
A solution (in this example solution of sodium chloride) freezes at a lower temperature than does the pure solvent (deionized water).
The higher the solute concentration (sodium chloride), freezing point depression of the solution will be greater.
Equation describing the change in freezing point:
ΔT = Kf · b · i.
ΔT - temperature change from pure solvent to solution.
Kf - the molal freezing point depression constant.
b - molality (moles of solute per kilogram of solvent).
i - Van’t Hoff Factor.
Dissociation of sodium chloride in water: NaCl(aq) → Na⁺(aq) + Cl⁻(aq).
Answer:
colloidal system liquid dispersed in gas.
This would decrease by 25 hope this helps !!
