    What is a very "well-mixed" mixture, having the "same" properties throughout?                                                    * If each container of substance is poured through a                   coffee filter, no particles would be left                     behind because it is well-mixed.                            

    • Suspension

    • Solution

    • Mixture

    • Solubility

    Correct Answer
    A. Solution
    Explanation
    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.

    What is a mixture in which "particles can be seen" and "easily separated" by settling or filteration?                                                                       *Particles would be left behind if the                             substance is poured into a coffee filter.                             Particles also settle out in the globe. 

    • Solution

    • Colloid

    • Suspension

    • Solute

    Correct Answer
    A. Suspension
    Explanation
    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.

    What is a mixture with

    What is a mixture with "small undissolved particles" that do not" settle out?                               Examples: fog, shaving cream, whipped topping                      

    • Colloid

    • Suspension

    • Solution

    • Supersaturated solution

    Correct Answer
    A. Colloid
    Explanation
    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.

    What is a mixture that has "a lot" of solute dissolved in it?                                                                      READ EXAMPLES BELOW                              BEFORE ANSWERING QUESTION!           Example 1:   If you by a small bottle of Tide detergent,                rather than buying the huge box, both will wash the            same number loads of laundry.           Example 2:  A small can of frozen orange juice when               mixing it with water will make the same amount as a large            container from the refrigerated area in the store, which is            already mixed before it is purchased. 

    • Solubility

    • Solution

    • Dilute solute

    • Concentration

    Correct Answer
    A. Concentration
    Explanation
    A mixture that has "a lot" of solute dissolved in it is referred to as a concentration. This means that there is a high amount of solute present in the mixture compared to the solvent. In the examples given, buying a small bottle of detergent or using a small can of frozen orange juice concentrate both result in a concentrated solution when mixed with water.

  • 6. 

    What is a mixture that has only a "little" solute dissolved in it?               Hint: Adding too little sugar or the lemonade mix                          to a glass of water makes it weak or _________.

    • Dilute solution

    • Saturated

    • Supersaturated solution

    • Neutralization

    Correct Answer
    A. Dilute solution
    Explanation
    A mixture that has only a "little" solute dissolved in it is called a dilute solution. This means that there is a small amount of solute compared to the amount of solvent. In the context of the hint given, adding too little sugar or lemonade mix to a glass of water would result in a weak or dilute solution, as the taste would be less concentrated.

    Rate this question:

  • 7. 

    What is a mixture in which "more" of the same solute can be dissolved?                Example:  A paper towel can still absorb more water                                without dripping water.

    • Dilute solution

    • Supersaturated solution

    • Saturated solution

    • Unsaturated solution

    Correct Answer
    A. Unsaturated solution
    Explanation
    An unsaturated solution is a mixture in which "more" of the same solute can be dissolved. In the given example, a paper towel can still absorb more water without dripping, indicating that the water is not fully saturated in the towel. Therefore, the correct answer is unsaturated solution.

    Rate this question:

  • 8. 

    What is a mixture that contains "as much solute in it as possible" at a given temperature?                       Hint: A paper towel is completely full of water, but                                not dripping any water.

    • Unsaturated solution

    • Supersaturated solution

    • Saturated solution

    • Concentrated solution

    Correct Answer
    A. Saturated solution
    Explanation
    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.

    What is a measure of

    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. Solubility
    Explanation
    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.

    • Acid rain

    • PH scale

    Correct Answer
    A. Acid rain
    Explanation
    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.

    • Dilute solution

    • Chemical digestion

    • Mechanical digestion

    • Digestion

    Correct Answer
    A. Mechanical digestion
    Explanation
    The process described in the question involves tearing, grinding, and mashing large food particles into smaller ones. This process is known as mechanical digestion, where physical actions such as chewing and the muscular contractions of the stomach and intestines break down food into smaller pieces. This is different from chemical digestion, which involves the use of enzymes and other chemicals to break down food molecules.

    What is a range of values from 0 to 14 which expresses the concentration or the most amount of substance of hydrogen ions in a solution? 0__________________7____________________14Most                            Neutral                                       Most Acidic                                                                            Base

    • Spring scale

    • Balance scale

    • Standard scale

    • PH scale

    Correct Answer
    A. pH scale
    Explanation
    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.

    What part of a solution is present in a "lesser" amount and "dissolved" by the greater amount of substance?                                                       Hint:  For example, the sugar.

    • Solvent

    • Solute

    • Solution

    • Suspension

    Correct Answer
    A. Solute
    Explanation
    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.

    What process changes "large" food molecules into "smaller" food molecules?                                          

    • Chemical digestion

    • Mechanical digestion

    • Digestion

    • Neutralization

    Correct Answer
    A. Chemical digestion
    Explanation
    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.
