Dinitrogen monoxide (N₂O; nitrous oxide) is a greenhousegas that enters the atmosphere principally from natural fertilize rbreakdown. Some studies have shown that the isotope ratios of ¹⁵N to ¹⁴N and of ¹⁸O to ¹⁶O in N₂O depend on the source, which can thus be determined by measuring the relative abundance ofmolecular masses in a sample of N₂O.(a) What different molecular masses are possible for N₂O?(b) The percent abundance of ¹⁴N is 99.6%, and that of ¹⁶O is 99.8%. Which molecular mass of N₂O is least common, andwhich is most common?
A mixture containing only A1203 (FM 101.96) and Fe203 (FM 159.69) weighs 2.019g. When heated under a stream of H2, Al203 is unchanged, but Fe203 is convertedinto metallic Fe plus H20 (g). If the residue weighs 1.774 g, what is the weight percentof Fe203 in the original mixture? Hint: The mass lost in the reaction due to oxygen(AM 16.00) will help you. a what is the equivalent amount of moles of oxygen from th preceding number? b. Mass of oxygen in the lost conversion reactiom above? c. Grams of Fe203 can be derived from the mass of oxygen? d. What is the wt% of Fe2O3 in the original sample?

You analyzed 2.475 g of a mixture of NaCl, SiO_22 and CaCO_33. You isolated 0.825 g NaCl, 0.825 g of CaCO_33 and 0.580 g SiO_22. You were told that the original mixture contained 35% NaCl, 45% CaCO_33 and 20% SiO_22. Calculate, compare, and offer an explanation for the difference in the composition of NaCl, CaCO_33 and SiO_22 you recovered. Explain. (Show all calculations in the space provided.)

When water is mixed with metals, a metal hydroxide is formed and oxygen gas is evolved. The evolution of the oxygen gas from the reaction of metals and water is indicated by the hastened consumption of the splinter. 2. Carbon dating is an application of nuclear chemistry where they use the amount of C-14 in a fossil to determine its age. Nuclear power plants produce radioactive wastes. 3. When water is mixed with oxides, hydrogen gas is evolved. A red to blue color change in the litmus paper indicates that the solution tested is an acid. 4. In the Winkler Titration Method, sodium thiosulfate is standardized against a known concentration of magnesium iodate. The normality (N) of a solution is always equal to its molarity (M). 5.
