Matthias wants to dissolve a solid sample of calcium chloride (cacl2), which is an ionic compound. which solvent will dissolve the sample of calcium chloride? solid copper water, a polar solvent hexane, a nonpolar solvent liquid mercury

The answer to your question is: water, polar solvent.

Explanation:

Data

sample of CaCl2

Solid copper this option is incorrect because in order to dissolve something the solvent must be liquid and this is a solid solvent.

water, I think this option is right, because CaCl2 is ionic and water is a polar solvent, CaCl2 will dissolve in water.

a polar solvent, CaCl2 will dissolve is a polar solvent like water, this option is correct.

hexane, CaCl2 will not dissolve in hexane because hexane is a non polar solvent and CaCl2 is ionic. This option is wrong

a nonpolar solvent This option is not right, CaCl2 will only dissolve in polar solvents.

liquid mercury, This option is wrong, mercury is not a solvent.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
