The molecular formula of butane is c4h10. it is obtained from petroleum and is used commonly in lpg (liquefied petroleum gas) cylinders (a common source of cooking gas). it has two arrangements of carbon atoms: a straight chain and a branched chain. using this information, draw the structure of the tertiary butyl radical that will form upon removal of a hydrogen atom.

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

Chromosome 17 is made of over million base pairs.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
