100.0 mL of 1.020 M HCl and 50.0 mL of 2.040 M NaOH, each at 24.53ºC, are mixed in a Styrofoam cup calorimeter. What is the final temperature of the mixture if the heat of acid-base neutralization (?Hneut) = ?57 kJ per mole of H2O formed? (Assume density of the solution = 1.00 g/mL and specific heat of the solution = 4.184 J/g•ºC, and assume an insignificant heat capacity of the Styrofoam cup)
Can someone continue on what I already have please. Water cannot be used as a solvent for the Diels-Alder reaction between maleic anhydride and 1,3-cyclopentadiene because
what is the volume of the drink (in mL) required to meet the RDA?
What is the theoretical yield in grams? What is the theoretical yield in moles? (I already have the calculated amounts of reactants) Just need theoretical yields.
Diethyl ether is a volatile organic compound. The vapor pressure of diethyl ether is 401 mm Hg at 18°C and the Hvap = 26.0 kJ/mol. Calculate the vapor pressure of diethyl ether at 40°C.
What is the pH of a 1.00 L solution which initially has 0.042 mol acetic acid and 0.020 mol sodium acetate once 0.006 mols of NaOH has been added.
what is the calculated value of partial pressure of o2 in acid mine water of ph 2 in which fe2+=fe3+.
You have 100 mL of a .10 M Acetate buffer pH 4.75 composed of .050 M Acetic Acid and .050 M Na Acetate. 100 ml of pure water is added and the pH is still 4.75. Use the henderson hasselbalch equation to explain what happened.
If an aqueous solution of iron(III) sulfate (a compound used in dyeing textiles and also for etching aluminum) is mixed with a solution of barium chloride, a precipitate of barium sulfate forms and the solution that remains contains iron(III) chlo..
