Answer:

The given statement is false.

Explanation:

A solution is defined as the solution in which the components gets completely dissolved in it. Particles are evenly spread in these solutions. These solution does not scatter light falling on it.

A colloid is defined as the mixtures when physical boundary is seen between the dispersed phase and dispersed medium. They scatter the light falling on it.

Particle size of solutions are smaller than that of the colloids.But size of colloids particles is smaller than the size of pores filter paper used in filtration process due to which they easily escape through filter and results in no separation.

Answer:

You need 8,324 g of CaCl₂ yo make this solution

Explanation:

Molarity is a way to express concentration in a solution, in units of moles of solute per liter of solution.

To know the grams of CaCl₂ it is necessary to know, first, the moles of this substance with the desired volume and concentration , thus:

0,1500 L × $\frac{0,500 mol}{L}$ = 0,075 CaCl₂ moles
