Explain A sample of an unknown gas effuses in 10.9 min. An equal volume of H2 in the same apparatus under the same conditions effuses in 2.18 min. Define what is the molar mass of the unknown gas?
Which of the following acid-base pairs would work best for a laboratory experiment requiring a pH of 6.8? What molar ratios of the compounds would you use to prepare the solution?
Give two reasons why ethuyl iodide is preferred over ethyl chloride in the Williamson ether synthesis.
The initial solution of B was 0.100 M and had a volume of 100.0 mL. Find the pH at the following volumes of acid added Va = 0, 5 ,10, and 15 mL.
The student uses 19.5 mL of 0.535 M NaOH to titrate the solution. Calculate the moles of acid neutralized per grams of tablet.
Which set of quantum numbers describes the highest energy electron found in the ground state of a Scandium atom?
Molecular Geometry The molecular geometry of a molecule describes the three-dimensional shape of just the atoms. This is in contrast to the electronic geometry, which describes the shape of all electron regions.
In the titration of a monoprotic acid with a solution of sodium hydroxide of known concentration, what quantities are equal at the equivalence point
When iron chloride FeCl3 is dissolved in water the solution becomes acidic. The preparation of the Fe(NO3)3 solution and the KSCN solution used 0.5 M HNO3 as the solvent instead of water. Explain why this was done. Hint: Consider Le Chatelier's Pr..
In this experiment we reduced methylene blue with ascorbic acid using HCl as a catalyst. Given that the half reaction for the reduction of methylene blue is MB+(ox) +2H +2e ----->MBH2(red) (potential = 100 mV)
