50mL of 0.10 M monoprotic acid dissolved in water and 50 mL of 0.10 M monoprotic base dissolved in water were mixed in a coffee-cup calorimeter (total V = 100mL, assume the contribution of the solutes to this total volume is negligible; assume the solution has the same density and the same specific heat as pure water). Pure water has a specific heat of 4.184 J/gK. The temperature increased by 3 degrees Celsius. Find AH in kJ / mol acid.​

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

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
