Answer:
The following are the four unusual characteristics of water due to hydrogen bonding:
1. Water exhibits high specific heat as the presence of hydrogen bonds enhances the concentration of energy needed for the molecules to accelerate the speed, thus, elevating the specific heat.
2. Water has both high melting and high boiling points as hydrogen bonds enhance the energy, which is needed at the time of phase change, thus, increasing both the melting and the boiling points.
3. The hydrogen bonds present in the water gives rise to robust intermolecular attractions, therefore, enhancing the surface tension.
4. The hydrogen bonds present in the water makes the water to exhibit high heat of vaporization, that is, of about 41 KJ/mol.
Answer: B) KCl
Explanation:
It is an odourless gas with a melting point of of 770°c and a boiling point of about 1420°c, it exists in a white crystalline solid form. KCl is highly water soluble and also soluble in other variety of polar solvent but insoluble in many organic solvents.
Answer:
2,325.6
Explanation:
By using the formula Q =mco
Q is the heat energy needed
M is the mass
C is the specific heat
O is the temperature change
Substitute the information that you get from the question in to the equation then you will find out the answer
The Answer is "None of the Above"
