3 0

Answer:

How do you calculate the average atomic mass of three isotopes?

To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses

2LiClO+KHSO - Li2SO4 + Cl2 + KOOH
agasfer [191]

Answer:

2.5 moles of KOOH are produced.

Explanation:

1)Given data:

Number of moles of KOOH produced = ?

Number of moles of LiClO = 5 mol

Solution:

Chemical equation:

2LiClO +  KHSO₄     →      Li₂SO₄ + Cl₂ + KOOH

now we will compare the moles of KOOH and LiClO.

                 LiClO          :          KOOH

                    2              :              1

                   5               :             1/2×5 = 2.5

2.5 moles of KOOH are produced.

White raven [17]

Answer:

Below answers are correct.

1) Dynamic equilibrium indicates that the amount of reactants and products are equal.

2) A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products.

3) Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction

Explanation: Dynamic equilibrium is also called reversible reaction because it moves both in farward as well as in backward direction. Dynamic equilibrium occurs when reactants convert into products and products convert into reactant at the same time. It only occurs when the reaction occurs in closed container.
