WebAlkanes are saturated hydrocarbons (substances composed solely of carbon and hydrogen, with only single bonds); alkanes have a general formula C H 2 + 2. Alkynes are hydrocarbons whose molecules contain a carbon–carbon triple bond; they have the general formula C H 2 – 2. fitbit lock screenWebAs you go up the fractionating column, the hydrocarbons have: lower boiling points lower viscosity (they flow more easily) higher flammability (they ignite more easily) This … can fruit get freezer burnedWebAlkanes are not very reactive and have little biological activity; all alkanes are colorless and odorless non-polar compounds. The relative weak London dispersion forces of alkanes result in gaseous substances for short carbon chains, volatile liquids with densities around 0.7 g/mL for moderate carbon chains, and solids for long carbon chains. fitbit login account sleepWebMar 23, 2011 · Fire is not an alkane or any substance in particular.
