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.

he solution is said to be an ideal solution, only when the intermolecular forces of attraction between A-A, B- B and A- B are ne
KengaRu [80]

Answer:True

Explanation:

A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.

Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.

Lets take A be the solute and B be the solvent  so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and  solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).

The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.

The enthalpy of mixing and volume of mixing of ideal solution is zero.

enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case  of ideal solutions it is zero.

Volume of mixing is change in volume on mixing a solute and solvent.

Of the five salts listed below, which has the highest concentration of its cation in water? assume that all salt solutions are s
Morgarella [4.7K]
Answer is: cobalt(II) hydroxide.
Ksp(lead(II) chromate) = [Pb²⁺][CrO₄²⁻]. [Pb²⁺] = √2,8·10⁻¹³ = 5,3·10⁻⁷ M.<span>
Ksp(cobalt(II) hydroxide) = </span>[Co²⁺][OH⁻]². [Co²⁺] = ∛1,3·10⁻¹⁵ = 1,1·10⁻⁵ M.
Ksp(cobalt(II) sulfide) = [Co²⁺][S²⁻]. [Co²⁺] = √5·10⁻²² = 2,23·10⁻¹¹ M.
Ksp(chromium(III) hydroxide) = [Cr³⁺][OH⁻]³. [Cr³⁺] = √(√1,6·10⁻³⁰) = 3,6·10⁻⁸.
Ksp(silver sulfide) = [Ag⁺]²[S²⁻].

Choose the products that complete the reaction NaHCO3+HC2H3O2
Novosadov [1.4K]

Answer:

The products will be;

CO₂ + H₂O + NaC₂H₃O₂

Explanation:

We are given;

Two reactants NaHCO₃ and HC₂H₃O₂

We are supposed to determine the products;

  • We need to know that hydrogen carbonates reacts with acids to give water, carbon dioxide and a salt as the products.

Therefore;

  • In this case, sodium hydrogen carbonates (baking soda) reacts with acetic acid to form water, carbon dioxide and sodium acetate.
  • The equation for the reaction is;

      NaHCO₃ + HC₂H₃O₂ → CO₂ + H₂O + NaC₂H₃O₂

  • Therefore, the products of the complete reaction between sodium hydrogen carbonate and acetic acid are CO₂ + H₂O + NaC₂H₃O₂

Why do we have thumbs?
alexandr1967 [171]

Answer:

According to Goog|e, "As the thumb is opposable, <u>it allows people to position it against other digits of the hand to manipulate or hold an object</u>. Some evidence suggests that this ability makes the thumb responsible for roughly 40% of the hand functions."

Explanation:

I hope this helps!
