Answer:

1.024 x 10⁻²²g

Explanation:

Data Given:

mass of copper = 63.5 g

no. of atoms of copper = 6.02 x10²³ atoms

mass of of an average copper = ?

Solution:

As 6.02 x10²³ atoms have 63.5 g of mass then what will be the mass of atom.

Apply unity formula

                     63.5 g of copper ≅ 6.02 x10²³ atoms of copper

                     mass of copper atom ≅ 1 atom of copper

Do cross multiplication

                     mass of copper atom = 1 atom x 63.5 g / 6.02 x10²³ atoms

                     mass of copper atom = 1.024 x 10⁻²² g

mass of an average copper atom = 1.024 x 10⁻²² g

A geologist discovers a fault in a massive rock while out in the field. He notices that the fault occurs at an angle and that th
Ludmilka [50]

Answer: normal fault

A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.  

On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.

A saturated solution of potassium chlorate is dissolved in 100g of water. If the saturated solution is cooled from 90 degrees Ce
dedylja [7]

Mass would crystallize out : 24 g

<h3>Further explanation </h3>

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility

  • 1. Temperature:
  • 2. Surface area:
  • 3. Solvent type:
  • 4. Stirring process:

We can use solubility graph to solve this.

solubility KClO₃ at 90°C=52 g

solubilty KCl₃ at 60°C= 28 g

Mass would crystallize out = 52 - 28 =24 g

Mole ratios how can the coefficients in a chemical equation be interpreted
navik [9.2K]

Answer:

The coefficient in a balanced chemical equation  indicates the mole ratio of both reactants and products.  

Explanation:

For example lets consider the reation between Hydrogen and Oxygen to form water:

2H2 + O2 ----------------------- 2H2O

In this reaction, the coefficients of the balanced reaction can be transformed to Mole ratio according to Avogadro's Law which states that at standard temperature and pressure, equal volume of gases contain the same  number of moles.

So the mole ratio for the above equation is  the  ratio of the coefficient:

2moles     :     1 mole               :          2 moles
