En el procesos de hidratación del carburo de aluminio (Al4C3 ), se obtiene gas metano (CH4 ) e hidróxido de aluminio, Al(OH)3 , de acuerdo a la siguiente reacción: Al4C3 + H2O → CH4 + Al(OH)3
Si se dispone de 9 moles de carburo de aluminio y 6 moles. Determinar: a) Reactivo limitante y reactivo en exceso. b) Los moles de Al(OH)3 que se obtienen.​

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
