Identify any solutes and solvents present in a mixture of 0.05 mol ethanol, 1 liter water, and 0.2 g hydrogen
Varvara68 [4.7K]

Answer:

Water is the solvent

Both the ethanol and the hydrogen peroxide are the solute

Explanation:

Both the hydrogen peroxide and ethanol are sisobable in water.

There are 0.05 moles of ethanol.

1 litreof water contains 55.55 moles of water.

0.2 g of hydrogen peroxide contains 0.2/34 = 0.0059 moles of hydrogen peroxide (the 34 is the molar mass of hydrogen peroxide).

Since there are more moles of water, water becomes the solvent and the other two liquids dissolve in it.

How does this equation help you to understand acids and bases: H+(aq) + OH-(aq)
KATRIN_1 [288]

Answer:

C. It shows you that the formation of water is a reversible reaction, which contains hydrogen and hydroxide ions.

Explanation:

The equation is

H₂O(ℓ) ⇌ H⁺(aq) + OH⁻(aq)

It also shows that water can behave as either an acid or a base, because it can produce both H⁺ and OH⁻ ions.

A and B are both wrong. Although the statements are correct, they don't say anything about acids and bases.
