Answer:
29.76ºC
Explanation:
The melting point is a physical property of the matter it doesn't change as you slice the gallium into three different parts. Thus, it's the same value 29.76ºC
Tell the teacher they have touched an unidetified liquid. This is because "hiro" can have a reaction with the chemical he touched that can harm his health.
The molar heat of vaporization of ammonia is 23.3 kJ/mol. The molar heat of condensation of ammonia is - 23.3 kJ/mol.
The molar heat of condensation is the opposite of the molar heat of vaporization. The molar heat of vaporization of ammonia is given :
ΔH evaporation = - ΔH condensation
Therefore the molar heat of condensation of ammonia is given by:
ΔH condensation = - 23.3 kJ / mol
That's right. The molar heat of vaporization of ammonia is 23.3 kJ/mol. The molar heat of condesation of ammonia is - 23.3 kJ/mol.
