Answer:

Cranberry Juice is a Homogeneous Solution.

Explanation:

A Homogeneous solution is identifiable as a solution that looks like it is one single fluid.

A heterogeneous solution would be categorized as a solution that is obviously two different compounds, like oil and water.

A colloid is similar to the way a homogeneous solution is identified, however, colloids have particles suspended in them that are 1 nanometer to 1 micrometer in length (If particles are smaller than 1 nanometer it is considered a homogeneous solution). Colloids can be identified by shining a flashlight into them. If the beam disperses, it's a colloid. If it goes straight through without dispersing, it's a homogeneous solution. A colloid example is Milk.

A Suspension is similar to a colloid, however, the particles in a suspension are larger than 1 micrometer. Particles in a suspension can often be seen with the naked eye, whereas Colloid particles cannot. A suspension's particles will often separate from the base solution in time. A suspension example would be shaking glitter up in a bottle of water.

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

When does a phyisical change occur?
ioda
Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances.
