Using two different methods, determine delta G degree at 25 degrees for the formation of POCl3 from its constituent elements P2(g)+O2(g)+3Cl2(g)--->2POCl3(g)
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.02 mL of 0.09352 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.13 mL. Balance the reaction below an..
What are the active ingredients & determine what possible tests to perform to identify each active ingredient. (what is the expected result?) - can't use melting points, boiling points, burning of solids, benedict's solution and tasting.
4NH3 + 5O2 yields 4NO + 6H2O Given 1.50g of NH3 reacts with 2.75g of O2 which is the limiting reactant?
Based on this equation, what is the value of the Rydberg constant (R) in m-1? (5 significant figures)
what will the final mixture contain if 14.0 g of N2 and 35.5 g of Cl2 react to completion and the balanced equation is: N2+3Cl2--->2NCl3
you mix 242 grams of NaCl with enough water to form 500 mL of solution. What is the final molarity?
What ions will the following elements form? Enter the letter of the item in Column Two that best matches the item in Column One.
In his explanation of the photoelectric effect, Einstein stated that the incident radiation had to have a minimum energy to dislodge the electron from the metal surface. This energy is called the work function.
What is the rate constant of a first-order reaction that takes 9.00 minutes for the reactant concentration to drop to half of its initial value?
propose two reasons why the results of some of your reactions in this lab do not agree with what is predicted using the established solubility riles.
The ph of 0.40 M HF(aq) is 1.93. Calculate the change in ph when 0.356 g of sodium fluoride is added to 50.0 ml of the solution .
For the reaction 2C6H6 + 15O2 → 3CO2 + 6H2O 30 grams of C6H6 are allowed to react with 79.09 grams of O2.
