Answer:
a.substitution
Explanation:
because one of the hydrogen atoms from the methane is replaced with a bromine atom.Alkanes undergo a substitution reaction with halogens in the presence of light. For example, in ultraviolet light , methane reacts with halogen molecules such as chlorine and bromine. This is a substitution reaction because one of the hydrogen atoms from the methane is replaced by a bromine atom.
Explanation:
P1V1 = P2V2
(100.7 kPa)(0.75 L) = (99.8 kPa)V2
V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)
= 0.757 L
