Standard airbags for automobiles used to implement the formation of sodium azide as a source of nitrogen gas. This has since been replaced due to the potential caustic nature of the products. The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen oxide in liquid ammonia: 3N2O(g) + 4Na(s) + NH3(l)→ NaN3(s) + 3NaOH(s) + 2N2(g) a.

The manufacture of nitrogen trifluoride is a growing industry, due to its use as a plasma etchant in the semiconductor industry. Nitrogen trifluoride can be synthesized by passing a current through a high-temperature mixture of ammonium fluoride and hydrogen fluoride, with hydrogen gas as a byproduct. In one synthesis, 1.20x10^3g ammonium fluoride is reacted with1.20x10^3g hydrogen fluoride to produce 5.00x10^2g nitrogen trifluoride. What is the limiting reactant, excess reactant, theoretical yield of nitrogen trifluoride, percent yield, and mass of excess reactant remaining after the reaction?

Melamine, C3 N3 (NH2)3, is used in adhesives and resins. It is manufactured in a two-step process in which urea, CO (NH₂)2, is the sole starting material, isocyanic acid, HNCO, is an intermediate, and ammonia, NH3, and carbon dioxide, CO2, gases are byproducts. In the first step of this reaction, urea is broken down into isocyanic acid and ammonia: ▼ Part A CO(NH2)2(1)—HNCO(1)+NH3(g) In the second step of this reaction, isocyanic acid reacts to form melamine and carbon dioxide: HNCO (1)→C3 N3 (NH2)3 (1) + CO2(g) Balance this reaction and enter the coefficients below. Enter the coefficients in order separated by commas (e.g., 1, 4, 5, where 1 indicates the lack of a coefficient). View Available Hint(s) Rev
