An equimolar mixture of nitrogen and acetylene enters asteady-flow reactor at 25 oC and 1.0 bar. The reaction taking placein the reactor is N2(g) + C2H2(g) = 2 HCN(g). The product leavesthe reactor at 600 oC and 1 bar and contains 24.2% of HCN by mole.Assuming that the gas mix in the reactor is an ideal gas with Cp =43.1 J/mol-K and that no heat loss occurred, how much heat issupplied to the reactor for each mole of N2 input?
What is the percentage chlorine by mass in the organic compound?" and got an answer of 37.1% Cl, which im pretty sure is right.
The carbon-14 in a living organism is constant until the organism dies after which carbon-14 decays with first-order kinetics as well as a half-life of 5730 years. Presume a bone from an ancient human contains 17.0% of the C-14 found in living org..
0.10M potassium chromate is slowly added to a solution containing 0.50 M AgNO3 and 0.05 M Ba(NO4)2. What is the Ag+ concentration when BaCrO4 just starts to precipitate. The Ksp for Ag2CrO4 and BaCrO4 are 1.1 x 10^-12 and 1.2 x 10^-10 respectively..
The answer is E. I'm confused doing the step by step procedure. I'm not sure why we use [H+]=10^-pH and Ka*Kb=Kw. What mass of potassium fluoride must be added to 500.0 mL of water to give a solution with pH = 8.07? [Ka(HF) = 7.1 × 10-4]
How many grams of dipotassium phthalate (242.3 g/mol) must be added to 700 mL of 0.175 M potassium hydrogen phthalate to give a buffer of pH 6.00?
What is the partition coefficent of 100 mg of benzoic acid in 2ml of methylene chloride and 2ml of water and 101 mg of benzoic acid in 30 ml of methylene chloride and 30ml of water
Problem- Reaction mechanism needed for reacting Guanidine Carbonate with 2,4-pentanedione using NaOAc to give the product 2-amino-4,6-dimethylpyrimidine.
Problem 1: Molecular orbitals and Valence Bond Theory: Why is O2 a paramagnetic species even though by VBT is should adopt a diamagnetic electronic structure? Use orbital diagrams or drawings to explain your answer.
Complete and balance the equations for each of the following reactions. Express your answer as a chemical equation. Identify all of the phases
if CO2 gas is collected over water at 25 degrees C and 775torr, what is the partial pressure of the CO2? The vapor pressure of water at 25degrees C is 23.8torr.
tripling the concentration of A increases the rate by a factor of 27, doubling the concentration of B has no effect on the rate, and tripling the concentration of C increases the rate by a factor of 3. Write down the rate law for this reaction.
Phosgene decomposes by the reaction COCL(g) CO(g) + Cl2 K2=8.3x10^-4 (at 360C) When 5.00 mol of COCL2(g) are placed in a 10.0 L flask, find the quilibrium concentration of COCL2, CO and CL2 using the follow steps
