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.
The answer is water.
That is water is added to cordial to make it more dilute.
Cordial is basically used to describe sweeter distilled spirits . Or it can be used to describe non-alcoholic drink. These drinks can be diluted using water.
So the answer is water, that is water is added to cordial to make it more dilute.
The answer should be; 11
The atomic mass number is found by combining the number of protons and neutrons
Hope this helps :)
