15 pts With the exception of one type of hydrogen atom, the atoms of all elements contain protons, neutrons, and electrons. • Identify the subatomic particle that determines the chemical identity of an atom of an element.
• Describe the characteristics of the subatomic particle that determines chemical identity.
• How is the atomic number of an element determined?

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

tobey

the answer would be b i believe
