What type of reaction takes place when potassium iodide reacts with chlorine gas?

Chemistry
1 answer:
Roman55 [17]3 years ago
4 0

Answer:

The correct answer is - d. single replacement or displacement.

Explanation:

The displacement or replacement reaction is the reaction in which the less reactive molecule or element is replaced by the more reactive element or molecule in the reaction. If there is only one replacement occurs its termed as a replacement or single replacement reaction.

In this case, if chlorine gas passes through the water solution of KI (potassium iodide), solid iodine and KCl are produced by the displacement or replacement reaction. Here iodine is less reactive so replaced by the more reactive chlorine.

                                 2KI(aq)+Cl2 (g)→2KCl(aq)+I2 (s)

Why do gases diffuse more quickly than liquids?
Alborosie

Answer:

D)Gas particles move rapidly and have space between them.

Explanation:

Matter exists in three states namely: solids, liquids and gases. The particles contained in these three states are different from one another. In the gaseous state, the particles are FAR APART from one another i.e. space exists and they move at a very fast rate in contrast to the particles of a liquid, which have less space and move slower.

This rapid movement of gas particles within a less restricted space accounts for the reason why gaseous substances DIFFUSE more quickly than liquids.

hoa [83]

Ans) 1.3 bison/mile

Soln:} See according to the question, Yellowstone National Park has an average of about 4500 bison living in it.

Area covered by Yellowstone park is 3472 miles.

So, to find the density of bisons living in Yellowstone Park we have to divide the no. of bisons by given area.

= 4500/3472

which is approximately 1.3 bisons per mile.

Therefore option a) is correct

Hope it helps!!!
