If solute ( Camphor) assigned were known, determination of the molar mass via frezzing -point depression could determine the identity. What other tests could have been performed on the unknown solute to determine identity?
The compound K2SiO 3 • χH2O is a hydrated crystal. It is analyzed for percent water in a procedure similar to the laboratory assignment with barium chloride
A 49g piece of ice at 0 degrees C is added to a sample of water at 9 degrees C. All of the ice melts and the temperature of the water decreases to 0 degrees C.
For a particular redox reaction Cr is oxidized to CrO42- and Cu2 is reduced to Cu . Complete and balance the equation for this reaction in basic solution.
Calculate the standard emf for each of the following reactions:a)H2(g) + F2(g)---> 2H+(aq) + 2F-(aq)
Your fuels group is experimenting with glassification of spent fuel. They want to know how much of the following constituents they need to buy to produce 1000 kgs of a glass containing
How many molecules of sucrose (table sugar), C12H22O11, dissolved in 450.0 g of water are needed to make a 1.30 m solution?
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
Assuming ideal-solution behaviour, what is the vapor pressure of the solution at 63.5°C? (c) What is the mole fraction of ethanol in the vapor above the solution?
how many millimoles of HNO3 are needed to react completely with a .2800 gram piece of copper wire.
determine how do you know if there must be a precipitate or not and Show whether or not a precipitate will form if The Ksp of PbI2 =9.8×10-9
A voltaic cell consists of a Hg/Hg2^2+ electrode(E degrees=0.85V) and a Sn/Sn^2+ electrode(E degrees=-0.14V). Calculate[Sn^2+]if [Hg2^2+]=0.36 M and Ecell=1.04V at 25 degrees C.
How would the following modifications of the experimental procedure used in this experiment affect the mass of the precipitate collected? Indicate whether the mass would be greater than, unchanges, or less than that obtained. Briefly explain the ..
