8.5 D Quiz #1

The names and chemical formulas of four substances are shown in the chart.
Which substance listed in the chart is made up of the most atoms?

A compound secreted by honeybees to paralyze intruders in their hive is known as 2-heptanone. The formula for this compound is shown.
How many atoms of each element are in one molecule of 2-heptanone?

Sulfur hexafluoride, SF₆, is a very stable, nonflammable gas at room temperature. It is used in many electronic products because it is a good electrical insulator.
Which statement describes the composition of sulfur hexafluoride?

The table lists some compounds found in foods and their formulas.
Based on this information, which of these statements is NOT true?

Students in a science class made ball-and-stick models of the substances they were studying. The key shows the elements the students used in their models.
Which model represents a compound containing at least one atom of carbon?

A student is using colored beads to make a model of aluminum sulfate, Al₂(SO₄)₃. Aluminum atoms are represented by blue beads, sulfur atoms by yellow beads, and oxygen atoms by green beads. Identify how many of EACH bead color you would need to model this compound.

Match up the formulas with the correct
