Zinc blende, or sphalerite, can be described as having a face-centered cubic unit cell with sulfur atoms at each lattice point a

nd four zinc atoms within the unit cell. What is the empirical formula for this material? Follow standard convention for writing an empirical formula (ex. for AlCl3 enter AlCl3 not Cl3Al).

Answer:

ZnS  

Explanation:

1. Number of Zn atoms

4 internal atoms = 4 Zn atoms

2. Number of S atoms

8 corners × ⅛ S atom/corner + 6 faces × ½ S atom/face = 1 S atom + 3 S atoms = 4 S atoms

3. Empirical formula

The atomic ratio is

4Zn:4S = 1Zn:1S

The empirical formula is ZnS.

Describe the major types of bodies of water
Alina [70]
<h2>Answer and Explanation </h2>

The body of water means the occurrence of water on earth’s surface. Examples are oceans,  lakes,  seas, ponds, and pools. The major bodies of water are:

  • Pacific ocean is the biggest and deepest of Earth's oceanic divisions. It stretches from the Arctic Ocean in the direction to the Southern Ocean.
  • Atlantic ocean is another giant of the world's oceans.  It includes nearly 20 percent of the Earth's exterior and nearly 29 percent of its water covering space.
  • The Indian Ocean is the third largest Ocean in the world. It is surrounded by Asia, Africa, and Australia.
  • Arctic ocean is the smallest and shallowest of the world's five main oceans.
  • Mediterranean sea is a sea is attached to the Atlantic Ocean.

Gas laws describe and predict the behavior of gases without attempting to explain why they happen
Nutka1998 [239]

The gas laws describe and predict the behavior of gases with an explanation and experimental data

So the given statement is False.

2) The volume of gas can be calculated based on Avagadro's law

It states that the volume of a gas is directly proportional or varies with the moles of the gas. Higher the moles more the volume, condition is the pressure and temperature are constants in the two conditions

Thus as here the pressure and temperature of nitrogen gas is kept constant

V α  moles

or

\frac{V1}{n1}=\frac{V2}{n2}

Where

V1 = 6 l

n1 = 0.50 mol

V2 = ?

n2 = 0.75 mol

On putting values

V2 = 6 X 0.75 / 0.5 = 9 L

so resulting volume of the gas will be 9L
