When you calculate the molarity and molality of the EDTA solution are the values very similar or not? Explain if this is what you might expect for a dilute aqueous solution with a density very close to 1.0 g/mL.
How much heat energy is required to raise the temp. of 0.363 kg of copper from 23.0 C to 60.0 C The specific heat of copper is 0.0920 cal /(g.C).
how many grams of ethylene glycol should you add to each liter of water? First convert the temperature to degrees Celsius, use the Kf vaule of 1.853 degrees C/molal for water, and recall that the density of water is 1.00 g/mL.
You respond to a 2AM liquefied compressed gas transportation accident which is leaking from a 5lb (2.3kg) steel cylinder. Chemical commodity on shipping paper is 5 lb RQ, compressed gas, flammable, toxic, n.o.s. (poison - inhalation hazard, zone B..
The complex ion Co(H2O)6(2+)(aq) is pink when placed in solution. Addition of chlorine ions creates an equilibrium with CoCl6(4-) in the solution, which is blue in color.
According to molecular orbital theory which of hte following is not predicted to exist I know its He2 but how do you get bond order from that is there an easy way
Further studies will refine how much water is needed for endangered species protection. States hope it will be the 130-150 KAF initially agreed upon rather than the 415 KAF the FWS thinks it is. What happen if cooperative agreement fails?
mass m in a one dimensional box of length L? If the answer is yes, then express the energy of this trial wavefunction in terms of h, m, and L?
If 15.0 mL of glacial acetic acid (pure HC2H3O2) is diluted to 1.70 L with water, what is the pH of the resulting solution? The density of glacial acetic acid is 1.05 g/mL
What are the frequency and energy of a photon with a wavelength of 900 nm. Report your answers to three significant digits.
A laser pulse with wavelength 555 contains 4.40 of energy. How many photons are in the laser pulse?
Draw the molecular orbital diagram for the acetylide anion (C22-). Assume that order of the n=2 molecular orbitals in increasing energy is
