A homogeneous mixture or solution consists of _____.
Fed [463]

Answer: Option (C) is the correct answer.

Explanation:

A mixture in which the components are evenly distributed or the components are present in same proportion throughout the mixture is known as a homogeneous mixture or solution.

As a result, there exists only one phase in the mixture. The components of mixture can be in solid, liquid or gaseous form.

For example, when sodium chloride (solid phase) is added in water (liquid phase) then it completely dissolve in it. Thus, there will be no boundary between the solute and solvent. Hence, it forms a homogeneous solution.

Therefore, we can conclude that a homogeneous mixture or solution consists of substances in more than one phase.

What is the pressure of a 3.5 mmol sample of ethane (C2H6) gas contained in a 0.500 L flask at 298 K?
-BARSIC- [3]
P = nRT/V

P = 3.5 x 10^-3 x 0.082 x 298 /0.5

P = 0.171 m Hg

P = 171 mm Hg

hope this helps

The solutions that are mixed contain agno3 and nacl. What two products can be formed by exchange of the ions from these two reac
anastassius [24]

Answer:

NaNO₃ and AgCl are the two products that can be formed.

Sodium nitrate, an aqueous solution and a solid silver chloride (precipitate)

Explanation:

We determine the dissociation of both salts

AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻ (aq)

NaCl (aq) →  Na⁺ (aq) + Cl⁻ (aq)

We make the ionic equation:

Ag⁺ (aq) + NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) → NaNO₃(aq) + AgCl (s) ↓

What is a ion and what is a isotope​
attashe74 [19]

Explanation:

an ion is an atom with a met electric charge due to the loss or gain of one or more electrons and an isotope can be in 2 forms of the same element that contain equal numbers of protons but a different numbers of neutrons in their nuclei and hence differ in relative atomic mass but not in chemical properties
