Acid halides react with atmospheric water to produce the corresponding- A. Amine B. amine salt C. amide D. carboxylic acid E. acid chloride
If the primary alcohol ethanol is subjected to sulfuric acid, an SN2 substitution would occur instead and diethyl ether would be formed.
When 0.100 mol of toluene(C7H8(l)) is burned in this calorimeter, the temperature is raised by 0.615C. The equation for the combustion reaction is
The gas-phase reaction Cl(g)+HBr(g) => HCl(g)+Br(g) has an overall enthalpy change of -66kJ. The activation energy for the reaction is 7kJ. What is the activation energy for the reverse reaction?
A 25.0-mL aliquot of vinegar was diluted to 250 mL on a volumetric flask. Titration of 50.0-mL aliquots of the diluted solution required an average of 34.88 mL of 0.09600 M NaOH. Express the acidity of the vinegar in terms of the percentage (w/v) ..
At a certain temperature, the solubility of potassium iodate, KIO3, is 41.1 g/L. Calculate its solubility product constant for this temperature.
Titration of an oxalate sample gave the following percentages of percent oxalate: 12.28%, 12.54%, and 12.24%. Calculate the average and the standard deviation.
Given stock solutions of 0.02 M tris pH 7.4 and 4 M NaCl, how would you prepare 10.0 ml of a 0.5 M NaCl, 0.01 M tris pH 7.4 (how many ml of tris, how many ml of NaCl, how many ml of water)
Chemists studied the formation of phosgene by sealing 0.73 atm of carbon monoxide and 0.98 atm of chlorine in a reactor at a certain temperature. The pressure dropped smoothly to 1.32 atm as the system reached equilbrium.
