Answer:

1.32×10²⁵ atoms of sulfate are contained in 22 units of it

Explanation:

1 unit = 1 mol

Al₂(SO₄)₃ → Aluminum sulfate

As 1 unit = 1 mol, 1 unit has 6.02×10²³ atoms of aluminum sulfate.

Let's make a rule of three:

1 unit of Al₂(SO₄)₃ contains 02×10²³ atoms

Then, 22 units of Al₂(SO₄)₃ must contain (22 . 6.02×10²³) / 1 = 1.32×10²⁵ atoms

What type of chemical bond involves the sharing of a pair of electrons by two atoms in a molecule.
Over [174]

Answer:

Covalent bond.

Explanation:

There are two kinds of chemical bonds: covalent bonds and ionic bonds.

  • A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
  • Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.

In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.

The atomic number of lead is 82. Its mass number is 207?.how many protons neutrons and electros does the atom of lead contain
kupik [55]

Lead have:

82 electrons

82 protons

125 neutrons

Explanation:

The number of electrons and protons are given by the atomic number of the element.

Lead have 82 electrons and 82 protons.

The number of neutrons are given by the difference between the mass number and atomic number.

For lead number of neutrons = 207 - 82 = 125.

Using your knowledge geologic processes, explain why there are fertile, nutrient-rich solls on and surrounding volcanoes
poizon [28]

Answer:

Hey, I will try my best

so as you know volcanos can be very destructive and cause mass death and deforestation. but nature needs volcanos because they are part of a cycle. The lava that comes from volcanos can feed various plants which will start to grow after an eruption. these plants will process the lava rock into food which feeds other plants. and soon enough you have a whole forest after all the lava rock has been processed.

How many atoms of mercury are present in 3.4 cubic centimeters of liquid mercury? the density of mercury is 13.55 g/cc?
maks197457 [2]

Answer:

             1.37 × 10²³ Atoms of Mercury  

Solution:

Step 1: Calculate Mass of Mercury using following formula,

                               Density  =  Mass ÷ Volume

Solving for Mass,

                               Mass  =  Density × Volume

Putting values,

                               Mass  =  13.55 g.cm⁻³ × 3.4 cm³                ∴ 1 cm³ = 1 cc

                               Mass  =  46.07 g

Step 2: Calculating number of Moles using following formula;

                               Moles  =  Mass ÷ M.mass

Putting values,

                               Moles  =  46.07 g ÷ 200.59 g.mol⁻¹

                               Moles  =  0.229 mol

Step 3: Calculating Number of Atoms using following formula;

                               Number of atoms  =  Moles × 6.022 ×10²³

Putting value of moles,

                               Number of Atoms  =  0.229 mol × 6.022 × 10²³

                              Number of Atoms  =  1.37 × 10²³ Atoms of Hg
