Answer: Option (a) is the correct answer.

Explanation:

Change in state of a substance occurs due to change in position of atoms by absorption or release of heat energy.

For example, ice is the solid state of water and when we keep it at room temperature then it absorbs heat from its surroundings. As a result, intermolecular forces of attraction between its molecules weaken.

Due to this particles or atoms gain kinetic energy and they tend to move away from each other.

Thus, we can conclude that a change from one state of matter to another involves the transfer of heat.

A sample of seawater contains 1.3 g of calcium ions in 3,100 kg of solution. what is the calcium ion concentration of this solut

IrinaVladis [17]

A unit of ppm has an acronym of parts per million. The equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:

mass Ca+ = 1.3 g = 1300 mg

ppm = 1300 mg / 3100 kg

Which statement best relates the strength and concentration of a base? At high enough concentrations, a weak base becomes strong

Lorico [155]

Answer: Option (b) is the correct answer.

Explanation:

When there are more number of hydroxide ions in a solution then there will be high concentration of $OH^{-}$ or hydroxide ions. As a result, more will be the strength of base in that particular solution.

A base is strong when it readily dissociate into its ions in the solution. When a base is strong, then it does not matter at what concentration it is dissolved in the solution because despite of its low concentration it will remain a strong base.

Thus, we can conclude that out of the given options, the statement even at low concentrations, a strong base is strong best relates the strength and concentration of a base.
