Each carbon-carbon sigma bond in the molecule allene (C3H4) is formed by the overlap of a ___ orbital on each end carbon with a ___ orbital on the central carbon.
A solution of acetic acid is 40% m/m with density = 1.045 g/mL. Calculate molarity, molality, and mole percent of the acid. Molecular weight of acetic acid = 60.05 g/mol
What is the total pressure, in mmHg, of a gas mixture containing argon gas at 0.25 atm, helium gas at 350 mmHg, and nitrogen gas at 360 torr
What is the volume of a unit cell of this metal? 4.What is the edge length of a unit cell of Fe?
50 mL of 0.1200 M hydroxyacetic acid (pKa = 3.83) are titrated with 0.1280 M KOH. What is the pH after the addition of 48.6 mL of the base
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0 M AgNO3 solution and a strip of cadmium metal in a 1.0 Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way.
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
In the laboratory a student finds that it takes 96.8 Joules to increase the temperature of 14.3 grams of solid diamond from 24.0 to 38.1 degrees Celsius.
You have 4.507 L of a 0.1572 M H3BO3 (boric acid, Ka = 5.800x10-10) solution. To convert this into a buffer having a pH of 9.3380, how many grams of KH2BO3 (M.W. 99.926) should be added to the solution?
Could you please explain to me the purpose and what's happening when we add the MTBE and then the NaHCO3? I know it has to do something with getting rid of carboxylic acid? and then getting rid of water
This experiment calls for the use of 2mL of 2-chloro-2methylpropane. The molar mass of 2-chloro-2methylpropane is 92.57g mol-1, and its density is 0.847g mL-1. 1) Calculate the number of moles of 2-chloro-2methylpropane used in this experiment.
For each species listed, indicate the hybrid orbital set (sp2, sp3d, etc) employed by the central atom
