The quantum mechanical model of the atom uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. So, this model is based on probability rather than certainty.

Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the
Alinara [238K]

Answer:

Electron loss is always associated with an increase in oxidation number- True

An exothermic reaction occurs when the energy required to break bonds in reactants is less than the energy released by bond formation in the products.  True

The concentrations of pure liquids and pure solids are never included in an equilibrium constant expression because such concentrations never change. True

Explanation:

Oxidation implies loss of electrons. When a specie looses electrons, its oxidation number increases. For instance; Fe(s) -----> Fe^2+(aq) + 2e implies an increase in oxidation number of Fe from 0 to +2.

In an exothermic reaction, the energy required to break the bonds in the reactants is less than the energy released when new bonds form in the products.

We do not include the concentrations of pure liquids and pure solids in the equilibrium constant expression because the concentration of these do not change significantly throughout the reaction.
