A pungent colorless gaseous alkaline compound of nitrogen and hydrogen NH3 that is very soluble in water and can easily be condensed to a liquid by cold and pressure
A deep wide-mouthed thin-walled vessel usually with a lip for pouring that is used especially in science laboratories
Bunsen burner
A gas burner consisting typically of a straight tube with small holes at the bottom where air enters and mixes with the gas to produce an intensely hot blue flame
A dark or black porous carbon prepared from vegetable or animal substances (as from wood by charring in a kiln from which air is excluded)
Something formed by a union of elements or parts; especially: a distinct substance formed by chemical union of two or more ingredients in definite proportion by weight
To remove bound water or hydrogen and oxygen from (a chemical compound) in the proportion in which they form water
To remove hydrogen from (a compound)

A white or yellowish white crystalline compound C20H14O4 used in analysis as an indicator because its solution is brilliant red in alkalis and is decolorized by acids and in medicine as a laxative
Potassium chlorate
A crystalline salt KClO3 that is used as an oxidizing agent in matches, fireworks, and explosives
Potassium nitrate
A crystalline salt KNO3 that occurs as a product of nitrification in arable soils, is a strong oxidizer, and is used especially in making gunpowder, as a fertilizer, and in medicine
Rubbing alcohol
A cooling and soothing liquid for external application that contains approximately 70 percent denatured ethyl alcohol or isopropanol
Spontaneous combustion
Self-ignition of combustible material through chemical action (as oxidation) of its constituents -- called also spontaneous ignition
