Atomic Emission Spectra Experiment
Gas sample = H2Emission lines: (Blue, Green, Red) Wavelengths for each emission line: Blue= 434.3575 , Green= 486.3128 , Red= 657.2626
1) As these lines are part of the Balmer series calculate the value of Rydberg constant.
2) Calculate the wavelength of light that corresponds to an energy of 7.78 x 10^-19 J
3) Calculate the energy of the electron in an Li^2+ atom with the electron in the third energy orbit.
A reaction is stereoselective when one stereoisomer is formed more than another.
when benzene c6h6 ofnbsp 780 g of molar mass 78 gmolnbspcombinesnbsp with 750 ml of concentrated nitric acid 16 m and
Question- How long would it take to deposit 1.36g of copper (Cu) from an aqueous solution of Cu(II) sulfate by passing a current of two amperes through the solution. Atomic mass of Cu is 63.546.
when most Fe+3 salts are dissolved in dilute nitric acid, the solution is often yellow to orange in color. Why could you not visually detect these colors in the Fe(NO3)3 stock solution?
Write net ionic equations for the reactions that take place when aqueous solutions of the following substances are mixed. Potassium fluoride and bromic acid. Ammonium Chloride and sodium hydroxide. Sodium cyanide and ammonium bromide
An aqueous solution containing 7%w/w of sodium carbonate is fed to the reactor at a rate of 100 kg min.1, where it mixes with a gas stream containing 70 mol% CO2 and 30 mol% air. All of the sodium carbonate in the feed reacts to form sodium bicarbona..
In a clock reaction 20.0mL of 0.200M KI, 20.0mL of 0.100M (NH4)2S2O8 and 10.0mL of 0.00500M Na2S2O3 were mixed in the presence of a starch solution indicator. The solution turned blue in 63.9 seconds.
describe an experiment that you could perform in lab that would provide the data so you could calculate the Ka value for sulfamic acid, HSO3NH2.
Use values of ksp and kf for copper (II) hydroxide and its complex to predict if a precipitate should form in a 0.1 M Cu2+ solution that is 3M in OH-
a) What us the change in momentum? Include magnitude and direction. b) What is the impulse acting on the car?
What are the electron configurations of the following metal ions: Fe3+, Zr4+ and Co3+. Draw a) the high-spin electron configuration for a complex containing Fe2+ and b) the low- spin electron configuration for a complex containing Fe2+. Assume an ..
Chapter 4 teaches us about how elements combine to form compounds. There are two main types of bonds that occur
