The 3 domains are archaea, bacteria, and eukaryote. It is a biological classification.
Answer:
True
Explanation:
The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -
COOH > OH > CO
COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.
Hence the given statement is true.
Answer: The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.
Explanation:

Initial Rate of the reaction = 0.100 M/s
Rate of disappearance of B:
![-\frac{1}{2}\frac{\Delta [B]}{\Delta t}=0.100 M/s](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5CDelta%20%5BB%5D%7D%7B%5CDelta%20t%7D%3D0.100%20M%2Fs)
![-\frac{\Delta [B]}{\Delta t}=2\times 0.100 M/s=0.200 M/s](https://tex.z-dn.net/?f=-%5Cfrac%7B%5CDelta%20%5BB%5D%7D%7B%5CDelta%20t%7D%3D2%5Ctimes%200.100%20M%2Fs%3D0.200%20M%2Fs)
The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.
