Why does the originally neutral hair and balloon become charged

1 answer:

3 0

Answer: Because When two objects, such as your hair and the balloon rub together, one loses some of its electrons to the other. This makes one object positively charged and the other object negatively charged. This movement of the electrons causes the neutral object to get a low positive charge.

If 0.600 mol of a nonvolatile nonelectrolyte are dissolved in 3.70 mol of water, what is the vapor pressure ph2o of the resultin

fredd [130]

To get the vapor pressure of the resulting solution, we use the Raoult’s Law:

Psolution = (χsolvent) (P°solvent)

1st: Calculate the mol fraction of the solvent. In this case, water is the solvent.

χsolvent = 3.7 mol / (3.7 mol + 0.6 mol)

χsolvent = 0.86

2nd: Calculate the vapor pressure.

Psolution = (0.86) (23.8 torr)

Psolution = 20.48 torr
