Question- (1) An electron in the n = 6 level of the hydrogen atom relaxes to a lower energy level, emitting light of λ = 93.8 nm. Find the principal level to which the electron relaxed.
(2) What is the velocity of an electron that has a de Broglie wavelength approximately the length of a chemical bond? Assume this length to be 2.9×10?10m

A carbohydrate is a compound composed solely of carbon, hydrogen and oxygen. When 7.7467 g of an unknown carbohydrate( = 180.1560 g/mol) was subjected to combustion analysis with excess oxygen, it produced 11.3546 g CO2 and 4.6481 g H2O. What is i..
During studies of the reaction below, 2 N2H4(l) + N2O4(l) ? 3 N2(g) + 4 H2O(g) a chemical engineer measured a less-than-expected yield of N2 and discovered that the following side reaction occurs
(FW 180.16 g/mol) is burned in a calorimeter whose heat capacity is 29.7 kJ/oK, the temperature increases by 2.635oK. Calculate the heat of combustion of fructose in kJ per mole.

Calculate the molarity of Ag in a solution resulting from the mixing of 30 mL of a 0.0250 M AgNO3 solution and 11.51 mL of K2CrO4
A solution containing the two compounds exhibits absorbances (using a 1.00cm cell) of 0.726 and 0.544 at 267 and 312nm, respectively. What are the concentrations of A and B in mg/mL? Note: The aborptivity values are given in units of L/g.cm.
Determine the atomic weight of your metal: Calculate the percent error for each using the atomic weight (literature) off of the periodic table:
The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive
