A chemist fills a reaction vessel with mercurous chloride solid, mercury (I) aqueous solution, and chloride aqueous solution at
makvit [3.9K]

Answer:

ΔG° = -533.64 kJ

Explanation:

Let's consider the following reaction.

Hg₂Cl₂(s) ⇄ Hg₂²⁺(aq) + 2 Cl⁻(aq)

The standard Gibbs free energy (ΔG°) can be calculated using the following expression:

ΔG° = ∑np × ΔG°f(products) - ∑nr × ΔG°f(reactants)

where,

ni are the moles of reactants and products

ΔG°f(i) are the standard Gibbs free energies of formation of reactants and products

ΔG° = 1 mol × ΔG°f(Hg₂²⁺) + 2 mol × ΔG°f(Cl⁻) - 1 mol × ΔG°f(Hg₂Cl₂)

ΔG° = 1 mol × 148.85 kJ/mol + 2 mol × (-182.43 kJ/mol) - 1 mol × (-317.63 kJ/mol)

ΔG° = -533.64 kJ

What is the first step of a ladybug during the growth and development process​
Sunny_sXe [5.5K]

Answer:

Damian here! (ノ◕ヮ◕)ノ*:・゚✧

The newly hatched larva is in its first instar, a developmental stage that occurs between molts. It feeds until it grows too big for its cuticle, or soft shell, and then it molts. After molting, the larva is in the second instar. Ladybug larvae usually molt through four instars, or larval stages, before preparing to pupate.

Explanation:

hope this helps? :))

What did Dalton’s atomic theory teach
sweet-ann [11.9K]

Answer:

  • All matter is composed of atoms.
  • Atoms are not destructible.
  • Compounds formation occur by the combination of one or different types of atoms
  • In the chemical reactions, atoms are rearranged.
  • The atom of the same elements are similar in size and properties and the Atoms of the different elements are different in size and properties.

Explanation:

  • <u>John Dalton has developed the Dalton atomic theory.</u>
  • Dalton atomic theory was the first to explain that all matters composed of atoms and its properties, the atom as the smallest particle which cannot be destroyed and damaged.
  • This theory was based on the <u>law of conservation of mass and law of constant composition.</u>
  • His theory was accepted by many scientists.
