Question

question 10 (1 point)
what happens when two bonded atoms are pushed closer so their nuclei nearly touch?

a attraction causes them to merge.

b the bond weakens as distance decreases.

c they bond more strongly.

d repulsive forces increase significantly.

question 11 (1 point)
when breaking bonds during a chemical reaction, what happens to energy?

a it is released into the surroundings.

b it remains constant.

c it is absorbed by the system.

d it is converted into light energy.

Explanation:

For Question 10: Atomic nuclei are positively charged. When two bonded atoms are pushed so close their nuclei nearly touch, the like charges create a strong repulsive force that dominates over any bonding attraction.
For Question 11: Chemical bonds are stable, energy-storing arrangements. To break these bonds, energy must be input and absorbed by the chemical system.

Answer:

Question 10: d. Repulsive forces increase significantly.
Question 11: c. It is absorbed by the system.
