Correct Answer
A. SoluteExplanation
In a solution, the solute is present in a "lesser" amount and is "dissolved" by the greater amount of substance called the solvent. The solute is the substance that is being dissolved, while the solvent is the substance that does the dissolving. Together, they form a solution. In this case, the sugar would be the solute and the water would be the solvent.Rate this question:

Correct Answer
A. SolutionExplanation
A solution is a very "well-mixed" mixture that has the "same" properties throughout. When each container of substance is poured through a coffee filter, no particles would be left behind because it is well-mixed. A solution is formed when a solute is dissolved in a solvent, resulting in a homogeneous mixture where the solute particles are evenly distributed at a molecular level. This uniform distribution of particles ensures that the solution has the same properties, such as color, taste, and composition, throughout.Rate this question:

Correct Answer
A. SuspensionExplanation
A suspension is a mixture in which particles can be seen and easily separated by settling or filtration. In this type of mixture, if the substance is poured into a coffee filter, the particles would be left behind, indicating that they are not dissolved. Additionally, particles in a suspension also settle out over time, forming a layer at the bottom of the container. Therefore, a suspension fits the description given in the question.Rate this question:

-
Suspension
-
Solution
-
Supersaturated solution
Correct Answer
A. ColloidExplanation
A colloid is a mixture that contains small undissolved particles that do not settle out. Examples of colloids include fog, shaving cream, and whipped topping. In a colloid, the particles are dispersed throughout the mixture and are not soluble in the solvent. This is different from a suspension, where the particles are larger and will eventually settle out, and a solution, where the particles are completely dissolved and evenly distributed. A supersaturated solution is a solution that contains more solute than it can normally hold, but it is not relevant to the given question.Rate this question:

-
Unsaturated solution
-
Supersaturated solution
-
Saturated solution
-
Concentrated solution
Correct Answer
A. Saturated solutionExplanation
A saturated solution is a mixture that contains as much solute in it as possible at a given temperature. This means that the solution is at its maximum capacity to dissolve the solute and any additional solute added will not dissolve. The analogy of a paper towel being completely full of water but not dripping any water illustrates this concept. Therefore, the correct answer is a saturated solution.Rate this question:

What is a measure of "how well a solute" can "dissolve in a solvent" at a given temperature?
-
Neutralization
-
Solubility
-
Digestion
-
Salt
Correct Answer
A. SolubilityExplanation
Solubility is a measure of how well a solute can dissolve in a solvent at a given temperature. It quantifies the ability of a substance to form a homogeneous solution with another substance. The higher the solubility, the more easily the solute can dissolve in the solvent. This property is important in various fields such as chemistry, pharmacy, and environmental science, as it determines the effectiveness of a substance in a solution. Neutralization, digestion, and salt are not directly related to the measure of solute dissolution in a solvent.Rate this question:

Correct Answer
A. Acid rainExplanation
Acid rain is more acidic than normal rainwater, with a pH level between 3 and 3.5. This type of rainwater contains higher concentrations of acidic pollutants, such as sulfur dioxide and nitrogen oxides, which are released into the atmosphere from industrial processes and vehicle emissions. When these pollutants mix with water vapor in the atmosphere, they form sulfuric acid and nitric acid, resulting in acid rain. Acid rain can have harmful effects on the environment, including damaging plants, aquatic life, and infrastructure.Rate this question:

What process changes "large" food molecules into "smaller" food molecules?
-
Chemical digestion
-
Mechanical digestion
-
Digestion
-
Neutralization
Correct Answer
A. Chemical digestionExplanation
Chemical digestion is the process that changes "large" food molecules into "smaller" food molecules. This process involves the breakdown of complex molecules into simpler ones through the use of enzymes and other chemicals. It occurs primarily in the stomach and small intestine, where enzymes break down proteins, carbohydrates, and fats into smaller molecules that can be absorbed by the body. Mechanical digestion, on the other hand, involves the physical breakdown of food into smaller pieces, but it does not change the chemical composition of the food molecules. Digestion is a broader term that encompasses both mechanical and chemical processes. Neutralization is unrelated to the process of breaking down food molecules.Rate this question:

-
Spring scale
-
Balance scale
-
Standard scale
-
PH scale
Correct Answer
A. pH scaleExplanation
The pH scale is a range of values from 0 to 14 that expresses the concentration or the most amount of hydrogen ions in a solution. A pH of 7 is considered neutral, meaning the solution is neither acidic nor basic. A pH below 7 indicates acidity, with lower numbers representing higher acidity. A pH above 7 indicates basicity, with higher numbers representing higher basicity. The pH scale is commonly used to measure the acidity or basicity of substances.Rate this question:
