Some alkenes have geometric (cis-trans) isomers because ________. all of the carbon atoms in the compound are rigid and cannot r
faust18 [17]

Answer:

the carbon atoms in the double bond cannot rotate

Explanation:

Isomers refer to molecules that have a distinct arrangement of the atoms in the molecule but have the same molecular formula.

Alkenes refer to a series of unsaturated hydrocarbons that contain ethylene and propylene.

Some alkenes have geometric (cis-trans) isomers because <u>the carbon atoms in the double bond cannot rotate</u>.

Consider the dissolution of calcium hydroxide:
Crazy boy [7]

Answer:

1. K_eq = [Ca^{2+][OH^-]^2 = K_{sp}

2. a. No effect;

b. Products;

c. Products;

d. Reactants

Explanation:

1. Equilibrium constant might be written using standard guidelines:

  • only aqueous species and gases are included in the equilibrium constant excluding solids and liquids;
  • the constant involves two parts: in the numerator of a fraction we include the product of the concentrations of products;
  • the denominator includes the product of the concentrations of reactants;
  • the concentrations are raised to the power of the coefficients in the balanced chemical equation.

Based on the guidelines, we have two ions on the product side, a solid on the left side. Thus, the equilibrium constant has the following expression:

K_eq = [Ca^{2+][OH^-]^2 = K_{sp}

2. a. In the following problems, we'll be considering the common ion effect. According to the principle of Le Chatelier, an increase in concentration of any of the ions would shift the equilibrium towards the formation of our precipitate.

In this problem, we're adding calcium carbonate. It is insoluble, so it wouldn't have any effect on the equilibrium.

b. Sodium carbonate is completely soluble, it would release carbonate ions. The carbonate ions would combine with calcium cations and more precipitate would dissolve. This would shift the equilibrium towards formation of the products to reproduce the amount of calcium cations.                                      

c. HCl would neutralize calcium hydroxide to produce calcium chloride and water, so the amount of calcium ions would increase, therefore, the products are favored.

d. NaOH contains hydroxide anions, so we'd have a common ion. An increase in hydroxide would produce more precipitate, so our reactants are favored.
