Answer #1

2. Butane- C​​​​​​4​​​​​H​​​10

Molar mass= 12 x 4 + 1 x 10

M = 58 g/ mol

3. It is always important that whenever we use any reagent it is at fixed temperature (mostly we consider room temperature). It allows uniformity during reactions. Thus, after tap water is processed to DI water it is not necessary that the temperature of the water will be the same as the room temperature and hence, it is collected and allowed to reach the room temperature first before carrying out any experiments.

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
