Draw the structure of hydrocarbon that reacts with 2 equivalents of H2 on catalytic hydrogenation and gives only succinic acid on reaction on acidic KMnO4
What would happen when the manganese dioxide MnO2 was added to the peroxide solution. why did this occure
What is the empirical formula of ascorbic acid, given that the pseudoformula is C3.41 H4.53 O3.41
calculate the average atomic mass in units of amu for iron fe given that the naturally occurring element exists mainly
The normal boiling point for H2Se is higher than the normal boiling point for H2S . This can be explained by larger dipole-dipole forces, larger dispersion forces, and larger hydrogen-bond forces for H2Se
suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag+, Ba2+, and Mn2+. the addition of HBr causes a precipitate to form
There are 3 different possible structures (known as isomers) for a dibromoethene molecule, C2H2Br2. One of them has no net dipole moment, but the other two do. Draw a structure for each isomer. Include H atoms.
Calculate O's aqueous solubility in surface waters of this lake. B.) Will the amount of O2 produced by photosynthesis cause O2's aqueous solubility to be exceeded in 1L of this lake water
The B4O5(OH)4^2- ion present in 5 ml of a saturated Na2B4O5(OH)4 solution at a measured temperature is titrated to the bromocresol endpoint with 3.25 ml of .291 M HCl.
After equilibrium has been established, 5.0 mg of o-xylene is measured in the water. What is the total mass of o-xylene present in the flask
if a lighter contains 2.5 ml of liquid butane den 0.8 gcm3 how much potential energy does the lighter contain
To obtain the same antifreeze protection requires 76 g of propylene glycol to replace each 62 g of ethylene glycol. Calculate the mass of propylene glycol required to replace 9.00 gal of ethylene glycol.
Hard water contains alkaline earth cations such as Ca2+ which reacts with CO32- to form insoluble deposits of CaCO3. Will a precipitate of CaCO3 form if a 250mL sample of hard water having [Ca2+] = 8.0x10-4M is treated with the following
