Answer: its the first one buster
A mole of an element refers to 6.02e23 atoms so they would have the same amount of atoms
Answer:
Option B
Explanation:
Salt is a non-volatile solute and hence adding salt will increase the boiling point of water and hence reduce the vapor pressure. While on the other hand, adding more water will require more time to boil and hence produce vapor and thus the vapor pressure. Shaking will also not help in increasing the vapor pressure. Thus, only increasing the temperature of the water will create more vapors at a faster rate and hence increase the vapor pressure.
Thus, option B is the correct answer
Answer:
Nitrogen
Explanation:
Nitrogen has 5 Valence Electrons.
And its atomic mass is also less than Bismuth.
There are other elements in the 5th row but this one has the lowest atomic mass compared to the others.
That statement is True
The components of a true solution consist of homogenous mixture which substance dissolved in a solvent. Later on, this components will blend with others and form new properties
hope this helps
