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.

Which statement(s) is(are) likely to be true about this cell?
Olin [163]

Answer:

B

Explanation:

As there are lots of mitochondria within the diagram it is very unlikely that diffusion occurs. only active transport occurs. cells within the root do not look like the diagram shown thus the statement I and IV are true.

Why is water essential to life on a chemical level?
babymother [125]
Well Water is essential to life for a number of reasons. It is a useful solvent that exists as a liquid at the ideal range of temperatures for life as we know it on Earth, behaving as a perfect medium across which biochemical reactions can occur. Your cells transport resources across the spaces within and between them facilitated by this medium, just as your blood serves as the ideal medium for transporting oxygen-carrying corpuscles and a rich soup of nutrients, hormones, and even waste products being sent for filtration. The very structure of your tissues is reliant upon water content; consider the difference between a fresh loaf of bread and a stale (dry)one that can be crumbled between the fingers. Plant cells, just like animals cells, require hydration to function, too. In fact, right down to unicellular life forms, life as we know it on this planet relies upon water existing as a liquid in order to function on a <span>biochemical level. I hope that helps you.</span>
