Answer: Option (d) is the correct answer.

Explanation:

It is known that a diamond is the hardest material according to Mohs scale. It also has highest thermal conductivity and that is why it is used in industrial applications.

It is used in the cutting and polishing of other tools or materials.  

Thus, we can conclude that out of the given options, using low-grade diamonds to cut materials is a common industrial use for a mineral.

What is a molecule???
ololo11 [35]
A molecule consists of group of atoms that are bonded together by chemical bond. It is the smallest particle of an element or a compound that has the properties of the element or the compound embedded in it. The atoms present in one element easily forms a bonding with the atoms of another element to form molecules. The size and complex nature of molecules varies hugely. Some molecules can have a single atom as is the case with helium, while in several other elements the number of atoms in the molecule can be more than one.

You perform recrystallization of 1 g of impure acetanilide from water. The solubility of pure acetanilide in hot water is 55g/L.
likoan [24]

Answer:

38.32 mL is minimal volume of hot water that is needed to dissolve 2.1 g of pure acetanilide.

Explanation:

Mass of acetanilide to be dissolved in hot water = 2.1 g

Mass of hot water to be used = m

Solubility of acetanilide = 55 g/L

This means that 55 grams of acetanilide dissolves in 1 L of hot water.

Then 1 grams of acetanilide will dissolve in :

\frac{1}{55}\times 2.1 L=0.0382 L

0.0382 L = 0.0382 × 1000 mL =38.2 mL

1 L = 1000 mL

38.32 mL is minimal volume of hot water that is needed to dissolve 2.1 g of pure acetanilide.

If you wanted to make 0.800 Liters of a 0.531 M solution of Nickel(II) chloride, NiCl2, how many grams of NiCIZ
kotegsom [21]

Answer:

<u></u>

  • <u>54.8g</u>

Explanation:

<u>1. Calculate the number of moles of NiCl₂</u>

a) Identify the known variables

  • V =0.800 liters
  • M = 0.531M
  • n = ?

b) Formula

       M=\dfrac{n}{V}

c) Clear n

        n=M\times V

<u>g) Substitute and compute</u>

         n=0.531M/times 0.800liters=0.4248mol

<u>2. Convert moles to grams</u>

a) molar mass of NiCl₂

  • 129g/mol (shown in the problem)

b) Unit canceling method

Use the factors in order to cancel the units to obtain grams

      0.4248mol\times 129\dfrac{g}{mol}=54.7992g

Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).

c) Round to 3 signficant figures

     54.8g
