Question

question 15 (1 point)
what part of the simulation corresponds to bond breaking?

a the simulation shows particles forming new bonds only.

b the simulation shows particles moving apart and separating

c the simulation shows a particle bouncing off the surface.

d the simulation shows particles moving closer together and interacting.

question 16 (1 point)
why doesnt the energy that goes into breaking bonds and that comes out when bonds are formed always balance out?

a it depends on the temperature.

b the reaction system is in equilibrium.

c energy is lost to the surroundings.

d the strength of the bonds being formed and broken differs.

Explanation:

For Question 15: Bond breaking involves the separation of particles that were previously bonded, so particles moving apart corresponds to this process.
For Question 16: The energy balance between bond breaking and forming depends on the difference in bond strengths; stronger bonds have more energy associated with them, so if broken and formed bonds have different strengths, energies do not balance.

Answer:

Question 15: b. The simulation shows particles moving apart and separating
Question 16: d. The strength of the bonds being formed and broken differs.
