State balanced equation for the instauration test of cyclohexene using the half-reaction MnO4 MnO2
Imagine that you have a 5.50 L gas tank and a 2.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch
This solution was back-titrated with a 0.0440 M Ga3 solution until all the EDTA reacted, requiring 12.0 mL of the Ga3 solution. What was the original concentration of the V3 solution?
you recrystallize 300 mg of solid material and obtain 200mg. what is your percent recovery. if you concentrate some of the mother liquor and obtain a further 40 mg, what is your total percent recovery
What is the mass in grams for each of the following: a) 5.12 mol of Al, b) .75 mol of Cu, c) 3.52 mol of MgBr2, d) 0.145l of C2H6O, e) 2.08 mol of (NH4)2SO4.
Write a balanced chemical equation for the reaction of 4-Nitrobenzaldehyde and sodium borohydride (NaBH4). If 0.21 g of 4-nitrobenzaldehyde dissolved in 10 mL of methanol is mixed with 0.14 g of sodium borohydride, what is the theoretical yield?
At 373 K, Keq = 2.39 for the following reaction: SO2Cl2(g) = SO2(g) + Cl2(g) In an equilibrium mixture of the three gases, the partial pressures of SO2Cl2 and SO2 are 3.31 atm and 1.59 atm, respectively.
