Use the octet rule to predict the formula of the compound that would form between tellurium and iodine, if the molecule contains only one tellurium atom and only single bonds are formed.
A flask is filled with vapor by boiling a volatile unknown liquid in the foil covered flask. As it boils away, the vapor of the unknown pushes the air out of the flask through a tiny pinhole opening and eventually the flask is filled with an atmos..
An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of 12.4°.
What is the pH of a 1.2 x 10-4 M solution of KOH? What is the hydronium concentration of this solution?
A sample of 0.50 moles of O2 gas initially at 250K and a pressure of 1.0 atm is compressed to final pressure of 12 atm. The compression can occur via two different paths
Use the van der Waals parameters for chlorine to calculate approximate values of (a) the Boyle temperature of chlorine and (b) the radius of a Cl2 molecule regarded as a sphere.
What is the freezing point of a solution made by dissolving 352g of ethylene glycol C2H6O2 on 648 g of water the freezing point of pure water is 0.0C and kf of pure water is -1.86Cm?
Calculate the mass fractions of the components in the mixture and the average molecular weight of the gas mix. b)The gases are mixed with 20% excess air and completely combusted with 100% conversion
Einstein stated that the incident radiation had to have a minimum energy to dislodge the electron from the metal surface. This energy is called the work function.
determine the freezing point depression, delta Tf, for the ionic solution. b. determine m effective for ionic solution. c. determine the van't Hoff factor, i, for the ionic compound.
Select the statements that correctly describe the regio- and stereochemical outcome of the hydroboration-oxidation reaction: (A) syn-addition of H-B species; (B) anti-addition of H-B species
Preliminary analysis suggests that the air stable form of setonium has a radius of 130 pm. Predict the formula of the form (cation, anion or oxide) in which it would likely be found in a beaker of pH 5.5 to 7 water.
The average person generates about 2500 Kcal of heat a day. How many kilowatt-hours of energy is this? If walking briskly dissipates energy at 500 W, what fraction of the day's energy does walking one hour represent.
