false
Explanation:
The more gravity pulls down on an object it gets heavier. Weight is just the amount of force gravity is putting on something. So if gravity is pulling it down more ut would get heavier.
Answer:
None of them, D
Explanation:
The actual answer is chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
Answer:
Mole fraction of Nacl is 0.173
Explanation:
we know that

where,
P
sol - the vapor pressure of the solution
χ solvent - the mole fraction of the solvent
P
∘
solvent - the vapor pressure of the pure solvent
This means that in order to be able to calculate the mole fraction of sodium chloride, you need to know what the vapor pressure of pure water is at
25
°
C You can use an online calculator to find that the vapor pressure of pure water at 25 C is equal to about 23.8 torr
.

=0.827
Also we know that

This means that the mole fraction of sodium chloride is
χ_{Nacl}= 1-Χ_{water}
= 1-0.827 =0.173
Answer: increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object.
