If the theoretical yield of a reaction is 22.7 g and the actual yield is 21.0 g , what is the percent yield?

Chemistry

4 0
Percentage yield = actual yield/theoretical yield

So divide 21.0 g by 22.7 g and multiply it by 100 to find the percentage yield

Consider the balanced equation below.
kondaur [170]

The option which gives the correct mole ratios is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

<h3 /><h3>What is Mole ratio ?</h3>

It is a conversion factor between compounds in a chemical reaction, that is derived from the coefficients of the compounds in a balanced equation

Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation

The balanced equation for given reaction is as follows ;

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

Molar ratio can be determined by the coefficients of the compounds in the balanced reaction

Coefficient is the number in front of the chemical compound and they are as follows

  • H₂S - 2
  • O₂ - 3
  • SO₂ - 2
  • H₂O - 2

Therefore, correct option is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

What is the equilibrium constant of pure water at 25°C?
ANEK [815]
The equilibrium reaction, causes the water dissociation constant, Kw, is 1.01 × 10-14<span> at 25 °C. That is because every H</span>+<span> (H</span>3O+) ion these forms accompanied by the formation of an OH-<span> ion, are the concentrations of these ions and in pure water the same thing can be calculated from </span>Kw<span>.

Galina-37 [17]

Explanation:

In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.

So, when at 298 K and 1 atm Br_{2} exists in liquid state and Cl_{2} exists as a gas then it means there occurs strong force of attraction between the molecules of Br_{2} due to which it exists in liquid form.

Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among Br_2 molecules are greater than those among Cl_2 molecules.
