Acetylene Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.

alkyne (āl'kīn') Any of a group of unsaturated hydrocarbons that havee carbon atoms in chains linked by one or more triple bonds and that have the general formula CnH2n-2. Alkynes can be solid, liquid, or gaseous and include acetylene. ◇ The group of alkynes as a whole is called the alkyne series or the acetylene series. The first five members of the alkyne series are acetylene (or ethyne), propyne, butyne, pentyne, and hexyne.

Heptane Application: n-Heptane is a straight-chain alkane consisting of seven carbons that is widely used as a completely non-polar solvent. n-Heptane is sometimes chosen as a less toxic option to the traditional hexane in appropriate processes. In liquid form, n-Heptane is very easy to transport and store.

ServSafe 6th Edition Chapters 5-9 If you do not know your elevation, it is best to check the accuracy of your thermometers using the ice-point method.) 1. Boil clean tap water in a deep pot. 2. Put the thermometer stem or probe into the boiling water so the sensing area is completely submerged. 3. Wait 30 seconds or until the indicator stops moving. 4. If the temperature is at 212 o F (100 o C) then remove the thermometer. It is ready for use.
