Hello, I've been asked to find the percent composition of 4 compounds (1 and 2 butanol, 1 and 2 bromobutane. The one I've provided is the GC of 2-butanol. How do I find percent composition of this compound?
Also, explain why the 4 reactions give you different product compositions by analyzing each of the reactions: what set of reaction conditions relate to what kind of product distribution and what does that tell you about the operating mechanism and the factors that affect product distribution?
If a solution is made by mixing 20.0 mL 0.3 M NaCH3COO with 30 mL 0.4 M CH3COOH, calculate the pH of the solution? For acetic acid, K = 1.76 x 10-5.
Estimate the pH at the equivalence point of an HOAc solution if 25.5 mL of this solution required 37.5 mL of 0.175 M NaOH to reach the equivalence point (Ka = 1.8 x 10-5).
vinegar contains 5.0 g of acetic acid, CH3COOH,in 100.0 mL of solution. Calculate the molarity of acetic acid vinegar.
