Question: What is the pH of 0.097 M of triethylammonium chloride (CH3CH2)3 NHCL?
I know that in order to solve this i need to find the Kb, which is equal to Kw/Ka, I know that Kw = 1E-14, but I do not know which Ka to use? Once i know the Kb, i will be able to solve this problem and find the pH, i just need help finding the appropriate Ka

You are given a description and 3 spectrum of an unknown compound and you are asked to identify it based off of the MS, IR, & NMR spectrum. All work must be shown with reasoning behind how the answer was found.
The problem is in the attachment below.
1. Solve each system by graphing.
y = - 2/3 x
2x + 3y = 5
2. Solve each system by the substitution method. Determine whether the equations are independent, dependent, or inconsistent.
2x - y = 4
2x - y = 3
3. Write a system of two equations in two unknowns for each problem. Solve each system by substation.
