Below are sample questions representative of the exercises included on this worksheet and related 5.6 Evidence of New Substances in Chemical Changes skill assessments:

Problem 1Difficulty: Mastery

Observation: A cold pack becomes cold after its inner pouch is broken. Which observation would best support a chemical-change claim?

AA change of state always creates a new kind of matter.

BA new substance forms whenever matter is moved from one place to another.

CAny change in size always proves a new substance formed.

DA temperature change can be evidence of a chemical change when substances react.

Solution & Explanation:Evidence of a new substance can include gas production, a new color or odor, light or heat production, a precipitate, or ash/rust. Changes in size, shape, or state are usually physical changes unless other evidence is present.

Problem 2Difficulty: Mastery

Observation: Two clear liquids mix and form a cloudy solid. Which observation would best support a chemical-change claim?

AA change of state always creates a new kind of matter.

BA new substance forms whenever matter is moved from one place to another.

CFormation of a solid precipitate can be evidence of a new substance.

DAny change in size always proves a new substance formed.

Problem 3Difficulty: Mastery

Observation: Wax melts near a flame but does not burn. Which observation would best support a chemical-change claim?

AA change of state always creates a new kind of matter.

BMelting wax is a physical change because the wax is still wax.

CA new substance forms whenever matter is moved from one place to another.

DAny change in size always proves a new substance formed.
