If you place a strong acid in water it will likely ionize. If you put the same acid in oil it will not. Why the difference?
denpristay [2]

Answer

An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. ex H₂SO₄

If you place strong acid into water it dissociate acid into H⁺ ions

Water is polar solvent(H⁺ and OH⁻), which has partial positive charge on one side and partial negative charge on the other side.

Strong acids readily dissociate in polar solvents to give H+ ions.

Where as Oil is a non polar solvent it has same charge all over so no dissociation of strong acid will take place.

A newly mated queen ant establishes a nest in an unoccupied patch of suitable habitat. Assuming that no disasters strike the nes
Alika [10]

Answer:

Logistic

Explanation:

As the newly mated queen inhabit the new habitat, the population of the ants would increase slowly first followed by a rapid increase in the population size. Once the population size reaches the carrying capacity, it is leveled off.

Carrying capacity is the maximum number of the individuals of a population that can be supported indefinitely by a habitat. Once the population reaches the carrying capacity, one or other required resources become limited which in turn does not allow the exponential growth of the population.

This type of population growth wherein the exponential increase is followed by leveling out the population as the carrying capacity is reached, is called logistic population growth.
