Answer:
Heptane > hexane> 3,3-dimethylpentane > butane
Explanation:
All things being equal, it is expected that the boiling point of the members of the alkane homologous series increase as we move down the group.
Hence for example, butane is expected to have a higher boiling point than ethane. Another important factor we would be considering in this answer is the presence of a branched alkane amongst the answers in the question. A straight-chain alkane will have a boiling point which is higher than that of a branched-chain alkane due to the greater surface area in contact, thus the greater van der Waals forces, between adjacent molecules
Now if we are to rank the compounds on the basis of boiling point, the answer is as follows:
Heptane > hexane > 3,3-dimethylpentane> butane
Answer: is a pure substance
Explanation:
ok im not full sure man but i would say multiple voltaic cells that have spontaneous half reactions
im sorry hope it helps
Answer:
of carbon dioxide gas.
Explanation:
Average distance covered by Americans in a day=
1 day = 24 × 60 min = 1,440 min
Average distance covered by Americans in a minute=
Average mileage of the car = 20 miles/gal = 32.18 km/gal
1 mile = 1.609 km
20 miles = 20 × 1.609 km = 32.18 km
Volume of gasoline used in minute =
(1 L = 1000 mL)
Mass of 86,320.00 gallons of gasoline = m
Density of the gasoline = d =
1 kilogram of gasoline gives 3 kg of carbon dioxde gas .
Then 303,882.84649 kg of gasoline will give :
of carbon dioxide gas.
