Decide whether or not each of the following metals dissolves in 1 M HCl . For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
1.) Ag2.) Al3.) Pb
If no reaction just say.
The atom then emits two photons: one of wavelength 1282.2 nm to reach an intermediate level and a second to return to the ground state. What was the wavelength of the second photon emitted?
if potassium bromide of 25.5 grams is dissolved in enough H 2 O to make 1750 mL of solution, determine the molarity of the solution?
Assume you 0.010 mol of N2O4 (g) in a 2.0L flask at 50 degrees Celcius. After the system reaches equilibrium, [N2O4] is 0.00090 M. What is the value of Kc for this reaction
The solvolysis of benzyl chloride proceeds via a carbocation intermediate and occurs more rapidly than the solvolysis of 2-chloro-norbornane and tertiary butyl chloride.
Calculate the number of formula units of the compound and the number of each ion in 3.75 moles of AlCl3.
When 0.052 mol of aluminum sulfate are dis- solved in enough water to make 179 milliliters of solution, what is the molar concentration of aluminum ions?
a 70g piece of ice at 0c is added to a sample of water at 6c, all of the ice melts and the temp of the water decreases to 0c, how many grams of water were in the sample?
What is the percentage purity of your ldh column fraction? 2. How many total mg of ldh are there in your column fraction?
Consider the halide ions as nucleophiles. Briefly explain why F-, the strongest base among the halide ions, is the best nucleophile in polar aprotic solvents while iodide the weakest base
Which byproduct would be obtained in high yield if the diazotization of p-toluidine were carried out at 30 oC instead of 0-5 oC
portion of that solution is diluted by adding 167 mL of water. What is the final concentration? Assume the volumes are additive.
the absorbance of the solution was found to be .5528. Based on the calibration curve of Y=26.1x + .081 (where absorbance is on y axis and concentration of product C is on the x axis) determine the equilibrium concentration of C, then using an ICE ..
