For the equilibrium CH3COOCH3(aq) + H2O ? CH3COOH + CH3OH Kc = 3.00 @ 298K If a solution initially contains 0.15 M acetic acid and 0.15 methanol calculate the equilibrium concentrations of ethyl acetate, acetic acid and methanol at this temperature. I dont know what im doing wrong im setting up an ICE table CH3COOCH3(aq) + H2O ? CH3COOH + CH3OH 0 0 0.15 0.15 -x +x +x i get .0225 + 0.30x+x^2 = 3.00 but i get both negative when i do the quadratic
An impure sample of potassium hydrogen phthalate, KHP, having a mass of 111.07 g was dissolved in water. This acid sample was neutralized by the addition of 310.0 mL of 0.250 M NaOH
When the flask was re-filled with an unknown gas, the same number of moles leaked out in 2.84 hours. Identify the unkown gas.
The concentration of the primary waste in the pond is 35 mg/L. All of a sudden, the process changes and the concentration of the waste in the stream coming into the pond jumps to 250 mg/L. The pond is 500,000 L and the flow rate of the waste comin..
The average person generates about 2500 Kcal of heat a day. How many kilowatt-hours of energy is this? If walking briskly dissipates energy at 500 W, what fraction of the day's energy does walking one hour represent.
A sample of 2-butanol containing 0.375 g in 12.5 mL of solvent was analyzed in a polarimeter using a 10.0 cm polarimeter tube. The sample had an optical rotation, ?, of -0.405. (A) What is the specific rotation of 2-butanol? (B) A sample of the en..
