An example of a solution is ___
-
Cement
-
Sugar and water
-
Sand and water
Correct Answer
A. Sugar and waterExplanation
An example of a solution is sugar and water. A solution is a homogeneous mixture in which one substance, called the solute, is dissolved in another substance, called the solvent. In this case, sugar is the solute and water is the solvent. When sugar is added to water, it dissolves and forms a clear, uniform mixture. This is an example of a solution because the sugar particles are evenly distributed throughout the water, resulting in a homogeneous mixture.Rate this question:

A general word equation for the above is: solute + ___________________ = solution
Correct Answer
solid, solvent, particlesExplanation
The general word equation for the formation of a solution is solute + solvent = solution. In this equation, the solute refers to the substance that is being dissolved, the solvent is the substance in which the solute is dissolved, and the solution is the resulting mixture. Therefore, the missing word in the equation is "solid," as it represents the solute in this context.Rate this question:

What is one property of a suspension that is different from that of a solution or a colloid?
-
Suspensions are colorless.
-
A suspension is always clear
-
If left to rest, the particles of a suspension will settle out
-
Colloidal solution has big particles
Correct Answer
A. If left to rest, the particles of a suspension will settle outExplanation
Suspensions are heterogeneous mixtures where solid particles are dispersed in a liquid or gas. Unlike solutions or colloids, the particles in a suspension are larger and can be seen with the naked eye. When a suspension is left undisturbed, the particles will eventually settle down due to gravity, resulting in a clear liquid above and a sediment at the bottom. This settling out of particles is a distinct property of suspensions that is not observed in solutions or colloids.Rate this question:

When this happens, the substance which dissolves is called the __________________.
-
Solvent
-
Solution
-
Solute
Correct Answer
A. SoluteExplanation
When a substance dissolves in a solution, it is called the solute. The solute is the component that is being dissolved by the solvent. In a solution, the solute particles are dispersed and surrounded by the solvent particles. Therefore, in this context, the correct answer is solute.Rate this question:

A solution that cannot hold any more solute at room temperature is _________
-
A weak solution
-
A concentrated solution
-
A saturated solution
-
Oil is a heavier solution
Correct Answer
A. A saturated solutionExplanation
A saturated solution is a solution that has reached its maximum capacity to dissolve solute at a given temperature. It cannot hold any more solute particles and any additional solute will not dissolve. This is different from a concentrated solution, which refers to a solution that has a high amount of solute relative to the solvent. A weak solution, on the other hand, refers to a solution that has a low amount of solute relative to the solvent. Therefore, the correct answer is a saturated solution.Rate this question:

Whipped Cream is an example of what?
-
Isotonic solution
-
Colloid
-
Suspension solution
-
None of the above
Correct Answer
A. ColloidExplanation
Whipped cream is an example of a colloid. A colloid is a mixture where one substance is dispersed evenly throughout another substance, but not dissolved. In the case of whipped cream, tiny air bubbles are dispersed throughout the liquid cream, giving it a light and fluffy texture. This is why whipped cream does not separate into distinct layers over time, unlike a suspension solution. It is also not an isotonic solution, which refers to a solution with the same concentration of solute as the surrounding environment.Rate this question:

Oil floats on water. The most accurate reason for this is
-
Oil is less dense than water.
-
Oil is immiscible (does not dissolve) in water.
-
Oil is both less dense and immiscible with water.
Correct Answer
A. Oil is both less dense and immiscible with water.Explanation
Oil floats on water because it is both less dense and immiscible with water. This means that oil is lighter than water and does not mix or dissolve in it. Due to its lower density, oil will naturally rise to the surface of water, creating a layer on top.Rate this question:

When most of the spaces between the solvent molecules are filled by the solute, what do you think will happen?
-
A suspension is formed
-
A solution is formed
-
A concentrated solution is formed
-
A colloidal solution is formed
Correct Answer
A. A concentrated solution is formedExplanation
When most of the spaces between the solvent molecules are filled by the solute, a concentrated solution is formed. This means that a large amount of solute has been dissolved in the solvent, resulting in a high concentration of solute particles in the solution. The solute particles are evenly distributed throughout the solvent, creating a homogeneous mixture.Rate this question:

What makes water such a good solvent?
-
Water is such a good solvent because it repels most molecules
-
Water is a good solvent because it has negatively charged electrons
-
Water is such a good solvent because it is such a small molecule
-
Water is such a good solvent because it's molecules have a strong chemical bond
Correct Answer
A. Water is such a good solvent because it is such a small molecule -
