A solution that conducts electricity very well is known as a
-
Electrolyte
-
Nonelectrolyte
-
Weak electrolyte
-
Solvent
Correct Answer
A. ElectrolyteExplanation
An electrolyte is a substance that conducts electricity very well. When dissolved in water or melted, electrolytes dissociate into positive and negative ions, allowing the flow of electric current. This is due to the presence of free ions that can carry charge. Examples of electrolytes include salt, acids, and bases.Rate this question:

What is the molarity of a solution that contains 30 g of NaOH in 500 mL of solution?
-
0.75 M
-
1.3 M
-
1.5 M
-
2.6 M
Correct Answer
A. 1.5 MExplanation
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution in liters. In this case, we need to convert the mass of NaOH to moles using its molar mass. The molar mass of NaOH is 22.99 g/mol for Na, 16.00 g/mol for O, and 1.01 g/mol for H, so the total molar mass is 39.99 g/mol. Dividing 30 g by 39.99 g/mol gives us 0.75 moles of NaOH. The volume of the solution is given as 500 mL, which is equal to 0.5 L. Dividing 0.75 moles by 0.5 L gives us a molarity of 1.5 M.Rate this question:

Adding salt to water will cause its freezing point to be ______0 degree C.
-
Lower than
-
Higher than
-
Same as
-
None of the above
Correct Answer
A. Lower thanExplanation
When salt is added to water, it disrupts the formation of ice crystals and reduces the freezing point of water. This phenomenon is known as freezing point depression. As a result, the freezing point of saltwater is lower than that of pure water. Therefore, the correct answer is "lower than".Rate this question:

As the temperature is increased, the amount of gas in soda ________
-
Increases
-
Decreases
-
Stays the same
-
None of the above
Correct Answer
A. DecreasesExplanation
As the temperature of soda increases, the gas molecules in the soda gain more energy and move faster. This increased movement causes the gas molecules to escape from the liquid more easily, leading to a decrease in the amount of gas present in the soda. Therefore, the correct answer is "decreases".Rate this question:

Which will dissolve more quickly when mixed with water?
-
Sugar granules
-
Sugar cubes
-
Both dissolve at the same rate
-
None of these
Correct Answer
A. Sugar granulesExplanation
Sugar granules will dissolve more quickly when mixed with water compared to sugar cubes. This is because sugar granules have a larger surface area exposed to the water, allowing for faster dissolution. On the other hand, sugar cubes have a smaller surface area, resulting in a slower dissolution rate. Therefore, when mixed with water, sugar granules will dissolve more quickly.Rate this question:

The component that dissolves the other component is called
-
Solvent
-
Solute
-
Mixture
-
Collide
Correct Answer
A. SolventExplanation
The correct answer is solvent. A solvent is a component that has the ability to dissolve other components, such as solutes, in a mixture. It is capable of forming a homogeneous solution with the other components, allowing them to disperse evenly throughout the solvent. In a solution, the solvent is typically present in a larger quantity compared to the solute.Rate this question:

The three types of solutions are:
-
Hypotonic
-
Isotonic
-
Hypertonic
-
Electrolytic
Correct Answer(s)
A. Hypotonic
A. Isotonic
A. HypertonicExplanation
The correct answer is hypotonic, isotonic, hypertonic. These terms refer to the concentration of solutes in a solution compared to the concentration inside a cell. A hypotonic solution has a lower solute concentration than the cell, causing water to enter the cell and potentially swell or burst. An isotonic solution has the same solute concentration as the cell, resulting in no net movement of water. A hypertonic solution has a higher solute concentration than the cell, causing water to leave the cell and potentially shrink or shrivel. The term "electrolytic" is not related to the types of solutions mentioned in the question.Rate this question:

The particles of solutions have a diameter of
-
Equal to 1 nm
-
More than 1 nm
-
Less than 1 nm
-
More than 2 nm
Correct Answer
A. Less than 1 nmExplanation
The correct answer is "less than 1 nm" because particles in a solution are typically very small and can range in size from a few nanometers to even smaller. Since the question asks for the diameter of the particles, it is reasonable to assume that the particles in the solution have a diameter smaller than 1 nm.Rate this question:
