The sign of the entropy change, ΔS, for the following processes include:

  • I2 (s) + ½ Cl2 (g) ← → ICl (g) - positive
  • 3 Ag (s) + 4 HNO3 (aq) → 3AgNO3 (aq) + NO (g) + 2 H2O (l) - positive
  • Cl2 (g) → Cl2 (l) - negative
  • C5H12 (g) + 8 O2 (g) → 5 CO2 (g) + 6 H2O (l) - negative

What is Entropy?

This is referred to the degree of randomness or disorderliness of a system and is denoted as S.

Entropy change is usually positive when solid or liquid reactant is converted into gas product and vice versa.

According to the research, the correct option is false, the statement related to a chemical reaction is false.

<h3>What is a chemical reaction?</h3>

They are reactions involving two or more substances (reactants), which change significantly in the process, and can consume or release energy.

Every chemical reaction subjects matter to a chemical transformation, altering its structure and molecular composition.

Therefore, we can conclude that according to the research, the correct option is false, the statement related to a chemical reaction is false.

What do chemists think is the best measurement of concentration for describing the concentration of a solid solute dissolved in
lara31 [8.8K]

Answer:

Molarity.

Explanation:

  • The molarity (M) of a solution is defined as the no. of moles of solute that dissolved in 1.0 liter of the solution.

M = (mass / molar mass) of the solute (1000 / volume of the solution).

<em>So, the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution is Molarity.</em>
