The vapor pressure of liquid diethyl ether, C₂H₅OC₂H₅, is 100 mm Hg at 262 K. A 0.167 g sample of liquid C₂H₅OC₂H₅ is placed in a closed, evacuated 300. mL container at a temperature of 262 K.

Calculate what the ideal gas pressure would be in the container if all of the liquid diethyl ether evaporated.  mm Hg

Assuming that the temperature remains constant, will all of the liquid evaporate? _____ yes or no

What will the pressure in the container be when equilibrium is reached?  mm Hg

Consider the following scenario:

You come across a "new" nutritional supplement that proclaims it to be a rich source of the same antioxidants commonly found in carrots, tomatoes and various peppers. You examine the product and note its appearance: a dark brown color might simply be from some type of syntehetic food dye. Since you have recently examined some of the antioxidants found in paprika in your organic lab, you decide to play "detective." So, show off your detective skills!

Outline a strategy for a simple experiment that will help you determine whether the manufactureer's claims are true or false.

A. NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is         0.030M in NH4Cl at 25 °C?

B. HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.045 M in NaClO at 25 °C?

Calculate the theoretical pH of the resulting solution when 0.25 mL of 0.100 M NaOH is added to 2.00 mL of an acetic acid/sodium acetate buffer (Ch3COOH/CH3CooNa - 1 ml of 0.1 M acetic acid and 1 ml of 0.10 M sodium acetate). Enter your answer in the box and show your work below. (pKa of CH3COOH = 4.74)

How many mL pf 1.07 M HClO4 should be added to 1.00 g of imidazole (C3H4N2; MW= 68.077 g/mol), a weak organic base (pKb= 6.95), to give a pH of 7.993?

A balloon filled with 39.1 moles of helium gas has a volume of 876 L at 0.0°C and 1.00 atm pressure. At constant pressure, the temperature of the balloon is increased to 38.0°C causing the balloon to expand. Calculate q, w, ∆E for the helium in the balloon. The specific heat of helium gas is 5.20 J/(g °C) and 101.3 J = 1 Latm.

Potassium chloride for injection comes in 60 ml vials containing 2 mEq/mL. how many milligrams of KCL are in each vial. im not sure what a mEq, is plus i need the steps on how to do the question. thank you

explain why the entropy of one mole of solid iodine at normal conditions is less than the entropy of one mole of gaseous chlorine at normal conditions

You have several identical balloons. You experimentally determine that a balloon will break if its volume exceeds 0.820 L. The pressure of the gas inside the balloon equals air pressure (1.00 atm).

(a) If the air inside the balloon is at a constant temperature of 21.8
