A list of changes is shown.
Temperature decreases
Intermolecular bonds become weaker
Freezing
Intermolecular bonds become stronger
Evaporation
Temperature increases
Vibration of molecules slows down
Molecules vibrate faster
Which of the above changes would be accompanied by an increase of the kinetic energy of particles in a liquid?
A, B, C, and H
A, C, D, and G
B, E, F, and H
B, C, F, and G
Answers
Answer:
b,c,f,g
Explanation:
it makes the most sense plus i just took the test <3 good luck
With an increase in the kinetic energy of the solid molecule the intermolecular bonds become weaker, temperature increases, melting and molecules vibrating faster are changes.
What is the effect of the increased kinetic energy?Kinetic energy is the form of the energy that is present in an entity in motion. When the kinetic energy is increased then the temperature of the particles increases and leads to evaporation.
The increased kinetic energy weakens the intermolecular bonds of the liquid particles and the molecules of the particles start vibrating fast.
Therefore, option b. intermolecular bonds become weak, option e. evaporation, option f. temperature increases and option h. molecules vibrate faster are the changes.

What is the mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride,ZnCI[subscript 2]?
[Relative atomic mass : Zn = 65]
Answers
Answer:
16.25g
Explanation:
Equation for the reaction = Zn + 2Cl = ZnCl2
1 molecule of Zn = 2 molecule of Cl
x mole of Zn = 0.5mol of Cl
mole of Zn = 0.25mol
mass of Zn = 0.25 * 65 = 16.25g
The mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride is 16.25g.
What is mass?Mass is the quantity of matter in a physical body.
The reaction is Zn + 2Cl = ZnCl₂
The ratio of moles of Zn and Cl
1 : 2
m, mol of Zn is equal to 0.5 mol of Cl
Moles of Zn = 0.25 mol
Multiply the mole of Zn and the relative atomic mass of Zn
Mass of Zn = 0.25 × 65 = 16.25 g.
Thus, the mass of zinc is 16.25 g.
