Below are sample questions representative of the exercises included on this worksheet and related 6.36 Physical Change versus Chemical Reaction and Conservation (Qualitative) skill assessments:

Problem 1Difficulty: Mastery

A student mixes two liquids and a solid forms. She filters and dries the solid, then dissolves it back into water. It does not turn back into the original liquids.

Which comparison best distinguishes the first formation from the later dissolving?

ABoth steps are physical because filtering was used, so no new substance can form.

BBoth steps are chemical because dissolving always creates new substances.

CThe first was physical because a solid appeared, and the second was chemical because it disappeared.

DThe solid forming was a chemical change (new substance made), which is why it cannot be separated back into the original liquids by simple physical means. Dissolving the dried solid is a physical change (spreading its particles in water). Conservation holds in both.

Solution & Explanation:The solid forming was a chemical change (new substance made), which is why it cannot be separated back into the original liquids by simple physical means. Dissolving the dried solid is a physical change (spreading its particles in water). Conservation holds in both. A physical change changes form, size, or state without making a new substance, while a chemical reaction forms new substances by rearranging atoms. Conservation of matter means the total amount of matter stays the same when you include the whole system (especially any gases that enter or leave).

Problem 2Difficulty: Mastery

A student measures the mass of a sealed container with vinegar and limestone chips before reaction. After reaction, the container mass is unchanged, but the pressure increased.

Which comparison best explains these results together?

APressure increase means new matter was created, so the mass should increase but the scale failed.

BMass staying the same proves no reaction happened; pressure must be imaginary.

CA chemical reaction produced a gas, increasing pressure. Because the container is sealed, the total mass stays the same (conservation); the gas is still inside as matter, just in a different form and data set.

DChemical reactions can change pressure but must destroy mass to do it.

Solution & Explanation:A chemical reaction produced a gas, increasing pressure. Because the container is sealed, the total mass stays the same (conservation); the gas is still inside as matter, just in a different form and data set. A physical change changes form, size, or state without making a new substance, while a chemical reaction forms new substances by rearranging atoms. Conservation of matter means the total amount of matter stays the same when you include the whole system (especially any gases that enter or leave).

Problem 3Difficulty: Mastery

A student leaves an open bottle of bleach solution for weeks and finds it is weaker. Another student says, “The bleach particles must have disappeared, so matter was destroyed.”

Which comparison best explains this using conservation?

AThe bleach became weaker only because matter disappears over time, breaking conservation.

BThe solution can undergo chemical changes over time (decomposition) producing other substances, and some products may escape as gases. Matter is conserved overall; particles did not vanish, they transformed and possibly left the bottle into the air.

CThe bleach became weaker because physical changes always destroy active ingredients.

DIt cannot be explained because conservation forbids any change in open containers.

Solution & Explanation:The solution can undergo chemical changes over time (decomposition) producing other substances, and some products may escape as gases. Matter is conserved overall; particles did not vanish, they transformed and possibly left the bottle into the air. A physical change changes form, size, or state without making a new substance, while a chemical reaction forms new substances by rearranging atoms. Conservation of matter means the total amount of matter stays the same when you include the whole system (especially any gases that enter or leave).
