Why is it useful to group elements based on the way they behave in chemical reactions?

1 answer:

8 0

<em>The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world. Group 18 elements, on the far right side of the table, for example, have completely full outer shells and rarely participate in chemical reactions.</em>

A solution contains 14 grams of KCl in 100. grams of water at 40°C. What is the minimum amount of KCl that must be added to make

pashok25 [27]

Answer:

1386g

Explanation:

Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.

if 14g dissolved in 100cm3

the amount that will dissolve in 1000cm3 = 14 x 1000/ 100

=1400g

To form a saturated solution, 1400 - 14 = 1386g must be added.

Calculate the concentration of the following solution in mol/dm3 0.1 moles of NaCl in 200 cm3

taurus [48]

1 $cm ^{3}$ = 0.001 $dm ^{3}$ . Therefore 200 $cm ^{3}$ = 0.2 $dm ^{3}$ . Molarity = $\frac{number of moles of NaCl}{volume of the solution} = \frac{0.1}{0.2} = 0.5 mol/dm^{3}$ . Hope this helps.
