The answer is- Gasoline - homogeneous, Soil- heterogeneous, Cranberry juice - homogeneous and Salt water-homogeneous.

Mixture: The substance that has two or more elements or compounds mixed together without binding them chemically is known as mixture.

The constituents of mixture can be separated by various methods.

What are homogeneous and heterogeneous mixture?

  • Homogeneous mixtures- Homogeneous mixtures are those that have same composition throughout its mass and there are no visible boundaries between its components.
  • Heterogeneous mixtures- When solute particles are not mixed uniformly in the solvent particles, then a heterogenous mixture is obtained.
  • Gasoline: It is a homogeneous mixture of various hydrocarbons.
  • Soil: Soil is a heterogenous mixture and its various components can be seen clearly.
  • Cranberry juice: It is also a homogeneous mixture as cranberry and water are mixed uniformly.
  • Salt water is also a homogeneous mixture as salt and water are mixed uniformly.

The correct answer is Gasoline [Homogeneous], soil[Heterogeneous], cranberry juice [Homogeneous], salt water [Homogeneous].

A mixture is a substance made up of two or more dissimilar chemical compounds that are not chemically linked in chemistry. When two or more substances are physically combined, their identities are maintained, and the mixture takes the shape of solutions, suspensions, or colloids. One or more pure components of differing compositions make up a combination. Heterogeneous and homogeneous mixtures are the two types of mixtures. While homogeneous mixtures seem consistent throughout, heterogeneous mixtures have clearly discernible components. A solution, which can be a solid, liquid, or gas, is the most typical kind of homogenous mixture.

Using standard heats of formation, calculate the standard enthalpy change for the following reaction.
Katena32 [7]

Answer:

ΔH°r = -483.64 kJ

Explanation:

Let's consider the following balanced equation.

2 H₂(g) + O₂(g)  ⇒ 2 H₂O(g)

We can calculate the standard enthalpy change of the reaction (ΔH°r) using the following expression.

ΔH°r = ∑ΔH°f(p) × np - ∑ΔH°f(r) × nr

where

ΔH°f: standard heat of formation

n: moles

p: products

r: reactants

ΔH°r = ΔH°f(H₂O(g)) × 2 mol - ΔH°f(H₂(g)) × 2 mol - ΔH°f(O₂(g)) × 1 mol

ΔH°r = (-241.82 kJ/mol) × 2 mol - 0 kJ/mol × 2 mol - 0 kJ/mol × 1 mol

ΔH°r = -483.64 kJ

Water freezes at 0∘C and CO freezes at −205∘C. Which type of intermolecular force accounts for this difference in freezing point
Assoli18 [71]

Explanation:

The dipoles in CO are in opposite directions so they cancel each other out, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces. Water (H2O) has hydrogen bond present which is a polar bond which has a high intermolecular force.

Water which has high intermolecular force will require more energy that is a higher temperature to overcome these attractions and are pulled together tightly to form a solid at higher temperatures, so their freezing point is higher.

As the temperature of a liquid decreases, the average kinetic energy of the molecules decreases and they move more slowly.

CO with lower intermolecular forces will not solidify until the temperature is lowered further.
