Analyze the diagram showing the changing states of matter. Drag the item from the item bank to its corresponding match.
iVinArrow [24]

The correct matches for changes of state are:

  • 1 or 3 : Arrow that shows particles getting closer together
  • gas: State of matter that would fill any container
  • liquid: State of matter with definite volume but NOT shape
  • 2 or 4: Arrow that shows particles gaining energy
  • solid: State of matter with definite shape

<h3>What is change of state?</h3>

Change of state is the process whereby matter in one physical state is converted to matter in another state by the addition or removal of heat.

The process of change of state are:

  • Melting: solid to liquid due to addition of heat
  • Vaporization: liquid to gas due to addition of heat
  • Sublimation: solid to gas due to addition of heat
  • Freezing: liquid to solid due to removal of heat
  • Condensation: gas to liquid due to removal of heat
  • Deposition: gas to solid due to removal of heat

Considering the given diagram, the correct matches are:

  • 1 or 3 : Arrow that shows particles getting closer together
  • gas: State of matter that would fill any container
  • liquid: State of matter with definite volume but NOT shape
  • 2 or 4: Arrow that shows particles gaining energy
  • solid: State of matter with definite shape

In conclusion, change of state of matter occurs due to heat changes.

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
