i really dont know and im so so so so sorry
The CH4 molecule has the lowest molecular weight, so it has the lowest boiling point.
Hope I helped :)
To fine volume, you have to divide the mass by the density of the substance. in this, you’ll do 19.6/7.83=2.50
Answer:
(C) Acetylene (ethyne) can be converted to the acetylide anion by treating with a strong base such as CH₃Li.
Explanation:
Acetylene (C₂H₂) can be converted to the acetylide anion (C₂⁻²) when treated with a base because it will donate protons (2H⁺). So it will be a neutralization reaction. NaNH₂ and NaOH are strong bases because they are good electrons donators ( NaNH₂ has pair of electrons on N, and NaOH has the group OH⁻), but CH₃Li has no pair of electrons to donate, so it's not a strong base.
