Calculate the frequency of each of the following wave lengths of electromagnetic radiation. Part A: 488.0 \rm nm (wavelength of argon laser) Part B: 503 {\rm nm} (wavelength of maximum solar radiation) Part C: 337.1 \rm nm (wavelength of nitrogen laser)
Calculate the percent relative error for the three solutions if perfect technique is used. Report the two new molarities. (The error in a 10-mL transfer pipet is 0.02, and the error in the 200-mL volumetric flask is 0.1)
Perform a series of experiments for the reaction A?B+C and find that the rate law has the form rate = k[A]x. Determine the value of x in each of the following cases.
how many liters of O2 can be made from 342 g H2O2 if the density of O2 is 1.428 g/L?
The annual production of zinc sulfide (ZnS) is 3.5 10^4 tons. Estimate the number of tons of SO2 produced by roasting it to extract zinc metal.
A mixture of NaBr and NaI has a mass of 1.620 g. When treated with excess AgNO3, it yields a mixture of AgBr and AgI which has a mass of 2.822 g. What mass of NaI was present in the original mixture?
Calculate the theoretical yield of C2H5Cl when 135 g of C_2H_6 reacts with 225 g of Cl_2, assuming that C_2H_6 and Cl_2 react only to form C_2H_5Cl and HCl.
Which of the molecules N2, NO, O2, C2, F2, and CN would you expect to be stabilized by (a) the addition of an electron to form the anion (b) the removal of an electron to form the cation
A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of a 2.18 g sample burns in excess oxygen yields 3.94 g of CO2 and 1.89 g of H2O. A separate experiment shows that a 1.23 g sample contains 0.235 g of N.
