Physical Chemistry Ideal Gas Problems 1.(20pts). What is the approximate mass of the earth's atmosphere. Recall Newton's 2 law is F=mass x acceleration and that the Area of a sphere is 4xr? Data: The radius of the earth is 6.37 x 10 m. Take the average pressure at the surface of the earth to be 1.00 atm, and the average acceleration due to gravity as 9.80665 m/s. List any additional assumptions that you make. 2.(20pts) (@) At 500.0°C and 699...

Synthesis of dimedone This lab exercise will give you practical experience with the generation of a malonic ester enolate and subsequent reaction with an a,p-unsaturated carbonyl compound. This sequence is known as the Michael reaction. In the presence of sodium methoxide, dimethyl propanedioate (malonic ester/dimethyl malonate) is converted to the corresponding enolate anion and reaction with 4-methylpent-3-en-2-one (mesityl oxide) affords the Michael adduct 1, as shown in the reaction sequence below. Under the basic reaction conditions, the Michael adduct 1...
