Answer:

The correct answer is option 4.

Explanation:

Substance which releases hydroxide ions(OH^-) in an aqueous solution are termed as bases.

Substance which releases proton (H^+) in an aqueous solution are termed as acids.

From the given options:

CH_3COOH : It is an weak organic acid known as acetic acid. Being acid it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow CH_3COO^-(aq)+H^+(aq)

CH_3COH : It is an alcohol named methanol and it is slightly acidic.They gives H^+ ions and alkoxiode ions.

CH_3COH(aq)\rightarrow CH_3CO^-(aq)+H^+(aq)

HCl : It is strong acid known as hydrochloric acid. Being highly acidic it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow Cl^-(aq)+H^+(aq)

KOH : It is strong base known as potassium hydroxide. Being highly acidic it releases [H&+] ion in an aqueous solution.

KOH(aq)\rightarrow K^+(aq)+OH^-(aq)

4- KOH

KOH is a strong base. In water it dissociates as 
<span>KOH--> K+ + OH- </span>
<span>A is acetic acid, a weak acid </span>
<span>CH3OH is an alcohol, weakly acidic in water </span>
<span>HCl is a strong acid.</span>

A large crystal of potassium magnet is placed in the bottom of a beaker with cold water and left for several hours
icang [17]

Answer:

Diffusion and Dispersion.

Explanation:

The two processes that took place in the given experiment are Diffusion and Dispersion.

When a crystal of potassium magnet is added placed in the bottom of a beaker which contains cold water, after 5 minutes the particles of potassium magnet will diffuse with water through diffusion process and the colour of water turns purple.

After few hours, the colour of solution goes light purple because the tiny particles which were diffused earlier will dispersed in the water and the particles will spread and make the solution lighter in colour.

Hence, the two processes are Diffusion and Dispersion.

How many moles of plutonium
bixtya [17]

0.139 moles of plutonium are present in a sample containing 8.4 x 10²² atoms of Pt.

<h3>How to calculate number of moles?</h3>

The number of moles of a substance can be calculated using the following expression:

no of moles = no of molecules ÷ 6.02 × 10²³

According to this question, 8.4 × 10²² atoms of plutonium are present in the molecule of plutonium.

no of moles = 8.4 × 10²² = 6.02 × 10²³

no of moles = 1.39 × 10-¹

no of moles = 0.139moles

Therefore, 0.139 moles of plutonium are present in a sample containing 8.4 x 10²² atoms of Pt.
