Answer:
Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.
Explanation:
When a gas is paced in a container, the molecules of the gas have little or no intermolecular interaction between them. There is a lot of space between the molecules of the gas.
The gas molecules move at very high speed and collide with each other and with the walls of container.
The collision of these particles with each other is perfectly elastic hence the kinetic energy of the colliding gas particles do not change.
Answer:
C) acid-base neutralization
Explanation:
NaOH + CH₃COOH = CH₃COONa + H₂O
Break the solutions apart:
NaOH = Na⁺ + OH⁻
CH₃COOH = CH₃COO⁻ + H⁺
Combine the resulting solution after the reaction:
OH⁻ + H⁺ = H₂O
