Answer:

The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process . The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure. (Below are listed tips)

- At absolute zero (0 K), the entropy of a pure, perfect crystal is zero.

- The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process.

- The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure.

Answer: H_2SO_4(aq)+2KOH(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)

Explanation:

Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate H^+ ions and bases donate OH^- ions in water which combine to form water molecules.

The balanced molecular equation is ;

H_2SO_4(aq)+2KOH(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)

G identify which substitution product is expected to be favored. explain. the product with retention of configuration is expecte
ddd [48]

The substitution product that is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.

<h3>What is a substitution product?</h3>

A substitution product is a product that is gotten from a reaction in which a group of reactants is replaced by another group in the reaction.

Therefore, the substitution product is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.
