Josh prepared an atomic model for his science project, as shown. Ruth observes the model and classifies it as a compound. Is Ruth’s classification correct?

• No. A compound is made of atoms of a single element that cannot be joined chemically.

• Yes. A compound is made of one or more similar atoms that may be joined chemically or physically.

• No. A compound is made of two or more atoms of different elements joined by bonds.

• Yes. A compound is made of only two similar atoms joined together by a bond.

Matter can be classified as having chemical and physical properties. Which step describes part of an experimental procedure that measures a chemical property of a substance?

• adding varying amounts of salt to one liter of water and heating it to measure the change in boiling point

• exposing a piece of iron pipe to varying levels of humidity in the air to measure the rate at which the iron rusts

• measuring the mass of a steel cube and finding its volume by water displacement to measure density

• placing a small sugar cube on a hot plate and warming it slowly to measure the melting point
