Answer:
CH3 - CH2 - NH - C(CH3)3
Explanation:
The 1HNMR is the acronym for Proton nuclear magnetic resonance and it is used in chemistry or Chemical laboratory for the analysis and identification of compounds.
In order to be able to answer the question accurately you have to have the tables containing all the values for chemical shift. The Chemical shift is measured in ppm and it occur due to Resonance frequency variation.
From the table, a singlet at 1.15 ppm (9H) is - C(CH3)3.
A singlet at d 0.9 ppm (1H) shows the presence of a secondary amine group, that is -R2NH group.
A triplet at 1.10 ppm (3H) shows that we have;
CH3- CH2-
A quartet at 2.6 ppm (2H) shows that we have;
-CH2 - CH3.
Therefore, joining all together we have;
CH3 - CH2 - NH - C(CH3)3.

Answer:
Initial concentration of HI is 5 mol/L.
The concentration of HI after is 0.00345 mol/L.
Explanation:
Rate Law:
Rate constant of the reaction = k =
Order of the reaction = 2
Initial rate of reaction =
Initial concentration of HI =
Final concentration of HI after t = [A]
t =
Integrated rate law for second order kinetics is given by:
The concentration of HI after is 0.00345 mol/L.
