Below are sample questions representative of the exercises included on this worksheet and related 9.13 Physical and Chemical Changes skill assessments:

Problem 1Difficulty: Mastery

Which explanation best connects HS-level particle reasoning to the everyday example of rusting?

AIron atoms at the nail surface combine with oxygen atoms to form iron oxide with properties different from iron

BRusting changes only the nail's shape, so particles are not involved

COxygen atoms become iron atoms when the nail gets wet

DRusting is physical because rust can be scraped off

Solution & Explanation:Rusting is chemical because atoms from different reactants combine into iron oxide. Scraping off rust does not change how the rust formed.

Problem 2Difficulty: Mastery

A planetary scientist describes ice on a comet subliming near the Sun while darker organic material on the surface reacts and forms new crust compounds. Which classification is most accurate?

ABoth processes destroy matter

BBoth processes are physical because they happen in space

CSublimation is physical, while formation of new crust compounds is chemical

DSublimation is chemical, while crust formation is physical

Solution & Explanation:Sublimation changes state without changing chemical identity. Formation of new compounds on the surface is chemical because new substances form.

Problem 3Difficulty: Mastery

A student observes bubbles when a solid cleaner is added to water. Which statement shows the strongest reasoning before classifying the change?

ABubbles mean chemical change, so no more evidence is needed

BBubbles mean physical change because water is present

CThe student should ignore the bubbles completely

DThe student should determine whether the bubbles are a new gas from a reaction or a gas previously trapped or dissolved

Solution & Explanation:Bubbles are evidence that must be interpreted. They may come from a chemical reaction or from a physical release of trapped or dissolved gas.
