Answer:
Ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.
Explanation:
The conversion factor to use in this case is:
charge / mass = 5.4 x 10^6 z / w
We are given that:
charge = 4.5 x 10^−15 z
Therefore the mass is calculated by combining the two
equations:
4.5 x 10^−15 z / mass = 5.4 x 10^6 z / w
<span>mass = 8.33 x 10^-22 w</span>
Answer:
Saturation.
Explanation:
Hello,
In this case, the statement is accounting for the saturation vapor pressure as it is the pressure of a vapor which is in equilibrium with its liquid, in other words it is the maximum exerted pressure possible by the vapor at a given temperature or just the maximum amount of the vapor, so there is neither no more vapor that could condense nor more liquid that could boil.
Best regards.
The answer is D. Triple only
Answer : The correct option is, kilogram of solvent.
Explanation :
Molality : It is defined as the number of moles of solute present in one kilogram of solvent.
Or, we can say that the number of moles of solute per kilogram of solvent.
The unit of molality is mole per kilogram or mole/Kg.
The formula will be :
Hence, the molality is a unit of concentration that measures the moles of solute per kilogram of solvent.
