This flask with a narrow neck is commonly used for mixing and heating liquids.

What is an Erlenmeyer flask?

This gas is produced in the violent reaction between Alkali metals and water.

What is hydrogen gas?

200

This general chemistry professor did their graduate work in astrophysics.

Who is Caldwell?

200

These two types of electromagnetic waves are directly adjacent to the visible range on the EM spectrum.

What are ultraviolet and infrared?

200

This alliterative heating element is commonly used in many labs.

What is a bunsen burner?

200

Sulfur hexafluoride (SF6) has this molecular geometry which remains an important factor in its relatively inert reactivity

What is octahedral

300

In the Volcano demo, we saw the following reaction: 4 (NH4)2Cr2O7 → 4 (NH4)2CrO4 + 2 Cr2O3 + 3 O2 In it, chromium undergoes this type of process.

What is an oxidation?

300

This professor, well-known for his obsession with the periodic table, was the previous department head.

Who is Brueckner?

300

The wavelength range of 590 - 610 nm is characteristic of this color

What is orange?

300

Titrations would be near-impossible without this piece of glassware

What is a burette?

300

This property, characteristic of many ionic salts, is the key factor that allows precipitation reactions to occur

What is dissociation into ions

400

What dye did we synthesize last week? 

Indigo

400

The chemistry department used to be located in this building prior to the construction of the current building in the late 1900s.

What is Austin OR Beach?

400

This type of reaction is responsible for the color change of phenolphthalein from white to pink.

What is acid base?

400

This shallow, circular glass is often used to hold solids or cover beakers.

What is a watch glass?

400

This type of energy defines the stabilization energy upon formation of an ionic solid structure.

What is lattice energy?

500

In our bouncy ball demo, we combined sodium silicate solution with ethanol. As a result, the sodium metasilicate (a polymer) underwent this process to become “goopy” and then bouncy!

What is polymer cross-linking?

500

Dr. Clyde Cady earned his Ph.D from this prestigious institution.

What is Yale?

500

This special connectivity of covalent bonds is one reason that compounds can appear colored.

What is conjugation?

500

This air-tight piece of glassware is the perfect home for moisture-sensitive chemicals.

What is a desiccator?
