Answer:
20 g/L
Explanation:
To know what happens with the concentration, we must calcute the limit of the function where t → ∞. The limit is the value that the function approach when t intend to a value. So:
![\lim_{t \to \infty} C(t) = \lim_{t \to \infty}\frac{20t}{360 + t}](https://tex.z-dn.net/?f=%5Clim_%7Bt%20%5Cto%20%5Cinfty%7D%20C%28t%29%20%3D%20%20%5Clim_%7Bt%20%5Cto%20%5Cinfty%7D%5Cfrac%7B20t%7D%7B360%20%2B%20t%7D)
Dividing both for "t"
![\lim_{t \to \infty} C(t) = \lim_{t\to \infty} \frac{\frac{1}{t}20t }{\frac{1}{t}(360 + t) }](https://tex.z-dn.net/?f=%5Clim_%7Bt%20%5Cto%20%5Cinfty%7D%20C%28t%29%20%3D%20%20%5Clim_%7Bt%5Cto%20%5Cinfty%7D%20%5Cfrac%7B%5Cfrac%7B1%7D%7Bt%7D20t%20%7D%7B%5Cfrac%7B1%7D%7Bt%7D%28360%20%2B%20t%29%20%7D)
![\lim_{t \to \infty} \frac{20}{\frac{360}{t} + 1 }](https://tex.z-dn.net/?f=%5Clim_%7Bt%20%5Cto%20%5Cinfty%7D%20%5Cfrac%7B20%7D%7B%5Cfrac%7B360%7D%7Bt%7D%20%2B%201%20%7D)
The limit of 1/t when t intend to infity is 0, which is demonstrated in the graph below, so:
![\lim_{t\to \infty} 20 = 20](https://tex.z-dn.net/?f=%5Clim_%7Bt%5Cto%20%5Cinfty%7D%2020%20%3D%2020)
The concentration will approach 20 g/L.

Answer:
3 H1 NMR signals
Explanation:
NB: kindly check the diagram of the chemical compound in the attached picture.
This particular Question is based on the part of chemistry which is known as spectroscopy. Spectroscopy is used in the Determination or in identifying chemical compounds. H'NMR works on the principle of nuclear magnetic resonance.
In order to solve this question, one has to count the number of hydrogen in unique location. The diagram in the attached show how hydrogen is been counted.
The numbers of signals is the number of different chemical environments in which hydrogen atoms are located.
NB: signals is also the same as peak in H'NMR.
Hence, the number of H1 NMR signals in this chemical compound is 3.
