What are the reactants and products of the synthesis of salicylic acid from methyl salicylate via saponification?
How would benzephenone move on a TLC compared to an alcohol? and WHY do they move differently.
How much heat is required to raise the temperature of a 7.40-g sample of iron (specific heat = 0.450) from 25C to 79.8C?
What volume of 0.1000 M NaOH is required to titrate a 0.1000 M propionic acid solution, CH3CH2COOH, Ka = 1.3 x 10-5 , to the equivalence point?
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structure of ClO4-
Metals Covalently Bonded to Benzene, Specifically interested to know why you don't see metals bonded to benzene with a covalent sigma bond. I am not interested in metal benzene complexes.
The iron content of an ore can be determined by a redox titration using K2Cr2O7 as the titrant. A sample of the ore is dissolved in concentrated HCl using Sn2+ to speed its dissolution by reducing Fe3+ to Fe2+.
35.5 grams of an unknown substance is heated to 103.0 degrees Celsius and then placed into a calorimeter containing 100.0 grams of water at 24.0 degrees Celsius.
What is the molar volume of the oxygen gas at the conditions in the laboratory?
The element lithium has two naturally occurring isotopes, 7Li (isotopic mass 7.0160 amu, abundance 92.5 %) and 6Li (isotopic mass 6.0151 amu, abundance 7.50 %). Calculate the atomic mass of lithium.
Suppose that in changing samples, a portion of the water in the calorimeter weere lost. In what way, if any, would this change the heat capacity of the calorimeter?
If iron(III) acetate is added to be 1 x 10^-10 M in a solution that is 0.10 M NH3, what is Qsp and will Fe(OH)3 precitate? the Ksp of Fe(OH)3 is 4x10^-38 and Kb for NH3 is 1.8x10^-5
