Adipic acid, H2C6H8O4, used to produce nylon is formed by the reaction of cyclohexane and oxygen: 2C6H12(l) + 5 O2(g) ? 2H2C6H8O4(l) + 2H2O (g) Assume that you carry out the reaction with 25.0 gr of cyclohexane (limiting reactant). What is the theoretical yield of adipic acid? If you obtain 33.5 gr of adipic acid, what is the % yield for the reaction?
A buffer solution contains 0.219 M CH3NH3Cl and 0.428 M CH3NH2 (methylamine). Determine the pH change when 0.097 mol HI is added to 1.00 L of the buffer.
Draw three possible structures for the B3H8- ion. Clearly indicate any three-center bonds. Which structure is most plausible (considering molecular orbital theory)
Select the strongest interparticle force(s) present in Mg3N2.
The item itself serves as the cathode, at which the Au^3+ ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit.
Suppose you were instructed to add 38 g of sodium chloride (NaCl) to 100 mL of water. a. prepared as instructed at 20°C b. heated the mixture in (a) to 100°C
how mamy moles of 1 chloroprppane (C3H7Cl) are produced if 352.grams of propane C3H8 react according to the equation
Calculate the pH at the points in the titration of 40.00 mL of 0.425 M NH3 for the reaction below. NH3(aq) + HNO3 NH4+(aq) + NO3?(aq) For NH3, Kb = 1.8x10-5.
Why do oxyacids become stronger when more oxygens are added. (as in the case of HNO2 being much weaker than HNO3)
need to generate ammonia from ammonium chloride to use in a reaction. should you use sodium bicarbonate or sodium carbonate?
What is the ay4- when edta is at ph of 10.5. is there a special trick when the ph is higher the pka6 equilibrium
Calculate k, Calculate also how long it would take for half of A to react. assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
How many moles of bromine will react with 0.0500 mole of C2H2 in the reaction C2H2 + 2 Br2 -> C2H2Br4?
