Answer:
1) Dispersion forces: It is a type of force which is present between atoms and molecules. It is a weakest intermolecular force that occurs between atoms. It is also called induced dipole-induced dipole attraction.
2. Dipole-dipole: It is a type of attractive force which is present between the negative end of one molecule with the positive end of another molecule. This type of attractive force occurs between polar molecules.
3) Hydrogen bond: It is a type of electromagnetic force which is present between hydrogen and high electronegative atoms such as nitrogen and oxygen etc.

Answer:
Total pressure = 1109.2 torr
Explanation:
Given data:
Partial pressure of cyclopropane = 334 mmHg
Partial pressure pressure of oxygen = 1.02 atm
Total pressure of mixture = ?
Solution:
Formula:
Total pressure = P of C₃H₆ + P of O₂
1 atm = 760 torr = 760 mmHg
1.02 atm × 760 torr / 1atm = 775.2 torr
Total pressure = P of C₃H₆ + P of O₂
Total pressure = 334 torr + 775.2 torr
Total pressure = 1109.2 torr
Let's apply the principle of conservation of energy.
Heat of metal = Heat of water
mCmetalΔT = mCwaterΔT
Applying the given values,
(45 g)(Cmetal)(100 - 28 °C) = (130 g)(4.18 J/g-°C)(28 - 25 °C)
Solving for Cmetal,
<em>Cmetal = 0.503 J/g°C
Therefore, the heat capacity of the unknown metal is 0.503 J/g</em>°C.
