The correct answer is option a, that is, they produce ions when dissolved in water.
The acids and bases refer to the chemical components, which reacts with water. The molecules of acids dissociate to give hydrogen ions to water, while the bases dissociate to provide hydroxide ions to the water, or that takes hydrogen ions from water and leave the hydroxide ions behind.

Answer:
Acceleration = 3.5 m.s⁻²
Explanation:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Given data:
Force = 35 N (N = Kg. m.s⁻²)
Mass = 10.0 Kg
a = ?
Formula:
a = F/m
a = 35 Kg. m.s⁻²/ 10.0 Kg
a = 3.5 m.s⁻²
Answer:
The same
Explanation:
In a saturated solution, the rate of dissolution is equal and the same to the rate of crystallization.
- A saturated solution of as substance (solute) at a particular temperature is one which contains the maximum amount of the substance that can dissolve at that temperature in the presence of the crystals of the substance.
- It is an equilibrium system in which a solid substance is in equilibrium with its own ions in solution.
- Therefore the rate of dissolution will the same with that of crystallization.
Answer:
O
Explanation:
The atoms lose energy during a change of state, but can still slide past each other; gas to a liquid.
