Answer 1

When substances are mixed, the total amount of a component can change, resulting in choice C being false.

Step-by-step explanation:

In a mixture of two or more substances, there are various changes that can occur depending on the nature of the components. However, there is one phrase that results in a false sentence, which is choice C. Contrary to this option, the total amount of a component can indeed change when substances are mixed together.

• Choice A: The concentration of a component might remain the same. This is true because even though the total amount of the component may change, its concentration can stay constant.
• Choice B: The total amount of a component might change. This is true as mixing substances can result in a change in the quantity of a component.
• Choice C: The total amount of a component does not change. This is false as mixing substances can definitely lead to a change in the total amount of a component.
• Choice D: The concentration of a component might change. This is true as mixing substances can alter the concentration of a component.
