Draw a synthesis of m-nitrobenzoic acid starting from Ethyl Chloride and utilizing any needed organic/inorganic reagents. Presume that a mixture of isomers can be separated.
If a reaction between Zn and I2 takes place, are the physical and chemical properties of the substances isolated during and after mixing the same as or different from those of Iodine and Zinc? Explain using the reaction as an example.
Proteins rich in disulfide bonds often require longer incubation times at higher temperatures before they denature. Why?
NH4NO3 absorbs 25.69KJ of heat per mole dissolved in water. In a coffee-cup calorimeter, 5.60 g NH4NO3 is dissolved in 100.0g of water at 22.0C(temp). What is the final temperature of the solution? Assume that the solution has a specific heat capa..
Illustrate the structures of the 6 bromoalkenes (with the molecular formula C5H9Br ) that have a branched C chain, and that show neither chirality nor E,Z isomerism.
What is the change in pH after addition of 10.0 mL of 1.0 sodium hydroxide to 90.0 mL of a 1.0 M NH3/1.0 M NH4+ buffer? [ Kb for ammonia is 1.8 x 10^-5]?
if 414 ml of a gas measured at 26degc and 641 torr has a mass of 0.384 g what are the molecular mass and molar
suppose that 45.0 g of water at 85degc is added to 105.0 g of ice at 0degc. the molar heat of fusion of water is 6.01
If the metal crystallizes in a body-centered cubic structure, which choice is closest to the atomic mass?
Write balanced, net ionic equations when the following compounds are mixed. Indicated mixtures where no reaction is expected with the notation no rxn.
predict the ratio of the two masses of oxygen that combine with a fixed mass of lead to form PbO and PbO2? PbO:PbO2 oxygen mass ratio= ?/?
What would be the pH if the same amount of HCl were added to the 125 mL of pure water? The Ka of acetic acid is 1.8*10^-5
why would it be difficult to determine the point where the limiting reactant changes if 13.0 ml of 1m hclaq were used
