6 0

Answer:

4 calcium ions and 4 sulfide ions.

Explanation:

In a face centered unit cell, 8 corners of the unit cell are occupied by 8 atoms. Each corner is 1/8 of a cell. In addition it has 6 atoms in the face of the lattice, which is 1/2 of a cell. (1/8 * 8) + (1/2 * 6) = 4. CaS has a 1:1 ratio. Therefore, they each have 4 ions.

Answer:

14. 13.2cg = 1.32dg

15. 3.8m = 0.0038km

16. 24.8L = 24800mL

17. 0.87kL = 870L

18. 26.01cm = 0.0002601km

19. 0.001hm = 10cm

Explanation:

14. 13.2/10 = 1.32

15. 38/1000 = 0.0038

16. 24.8(1000) = 24,800

17. 0.87(1000) = 870

18. 26.01/100000 = 0.0002601

19. 0.001hm(10000) = 10

An easy way to do these by yourself is to familiarize yourself with what each prefix means. Once you do this, you can multiply the value of the prefix when converting from a smaller unit of measurement to a larger one and divide the value of the prefix when converting from a large unit of measurement to a smaller one.

4. When you stir in the maximum amount of solute that will dissolve in a solvent, the solution becomes
VladimirAG [237]

Answer: Option D) Saturated

Explanation:

A solution is said to be saturated when it contains as much solute as it can dissolve at that temperature. Hence, if more solute is added, it will not dissolve.

Thus, a saturated solution has the maximum amount of solute that will dissolve in a solvent.
