Answer: D. A buildup of mostly methane gas, which is pontentially explosive.
Explanation:
Firedamp refers to a gas mixture, largely methane, that appear in underground coal mines. It is explosive at concentrations between 5 and 10% in the air.
Answer:
It describes length of measurement...
Answer:Benzene typically undergoes reactions in which the aromatic ring is preserved.B. Benzene typically reacts with electrophiles where an aromatic proton is substituted by the electrophile
Explanation:
The reactions of benzene are such that the aromatic ring is not destroyed. Addition reactions destroy the aromatic ring hence they aren't typical reactions of benzene. Benzene rings are attacked by electrophiles in which reaction a proton is substituted by the electrophile. Alkenes only undergo addition reaction and not electrophilic substitution reaction.

Answer:
THE NEW VOLUME AT 1 K IS 1.2 L
Explanation:
Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.
Mathematically written as;
V1/T1 = V2/T2 at constant pressure
V1 = Initial volume = 6L
T1 = initial temperature = 5K
T2 = Final temperature = 1K
V2 = final volume = unknown
Re-arranging the equation by making V2 the subject of the equation, we obtain;
V2 = V1 T2 / T1
V2 = 6 * 1 / 5
V2 = 1.2 L
The new volume of the gas sample at 1 K is 1,2 L
