pshichka [43]

Answer:

B) number of electrons

Explanation:

The two species:

          K+   and Cl- have the same number of electrons.

A neutral atom of K has 19 electrons

A neutral atom of Cl has 17 electrons

Now,

 To form K+, K will have to lose an electron and then the number of electrons becomes 18

To form Cl-, Cl will have to gain an electrons and then the number of electrons becomes 18

So, therefore, the number of electrons on both species is 18

AnnZ [28]

Answer: increase

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

As soda contains carbon dioxide dissolved in water.

The equation given by Henry's law is:

C_{CO_2}=K_H\times p_{CO_2}

where,

C_{CO_2} = solubility of carbon dioxide in water

K_H = Henry's constant

p_{CO_2} = partial pressure of carbon dioxide

Thus on increasing the pressure, the solubility of carbon dioxide also increase.
