Matthias wants to dissolve a solid sample of calcium chloride (cacl2), which is an ionic compound. Which solvent will dissolve t
miv72 [106K]

Answer:

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.

A waterbed mattress has the following dimensions: 210 cm X 160 cm X 25 cm. The density of water is 62.4lb/ft3. What is the weigh
artcher [175]

<u>Answer:</u> The weight of water bed in pounds is 1850.16 lb

<u>Explanation:</u>

To calculate the volume of cuboid, we use the equation:

V=lbh

where,

V = volume of cuboid

l = length of cuboid = 210 cm

b = breadth of cuboid = 160 cm

h = height of cuboid = 25 cm

Putting values in above equation, we get:

V=210\times 160\times 25=8.4\times 10^5cm^3=29.65ft^3      (Conversion factor:  1cm^3=3.53\times 10^{-5}ft^3 )

To calculate the mass of waterbed, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of waterbed = 62.4lb/ft^3

Volume of waterbed = 29.65ft^3

Putting values in above equation, we get:

62.4lb/ft^3=\frac{\text{Mass of waterbed}}{29.65ft^3}\\\\\text{Mass of waterbed}=(62.4lb/ft^3\times 29.65ft^3)=1850.16lb

Hence, the weight of water bed in pounds is 1850.16 lb
