4. Nitrogen monoxide is formed primarily in car engines, and it can react withoxygen to form gaseous nitrogen dioxide. Nitrogen dioxide forms nitric acidwhen it comes in contact with water, another component of acid rain. If 3.12 gof nitrogen monoxide reacts with 4.15 g of oxygen, how much nitrogen dioxidewill form? What is the limiting reagent? Which reactant remains in excess, andin what mass?2NO(9) + Ozig) → 2NO2(9) 5. Sodium nitrate decomposes to give sodium nitrite and oxygen.NaNO3 > NaNO2 + O2If 30.0 grams sodium nitrate decompose, how many grams of each product will beproduced?

The chemical reaction : 2NO(g) + O2(g) ----> 2NO2(g) Mass of NO (nitrogen monoxide) = 3.12 g…

Answered: 4. Nitrogen monoxide is formed…

In a common experiment in the general chemistry laboratory, magnesium metal is heated in air to produce MgO. MgO is a white solid, but in these experiments it often looks gray, due to small amounts of Mg3N2, a compound formed as some of the magnesium reacts with nitrogen. Write a balanced equation for each reaction.
Polychlorinated biphenyls (PCBs) have been used extensively as dielectric materials in electrical transformers. Because PCBs have been shown to be potentially harmful, analysis for their presence in the environment has become very important. PCBs are manufactured according to the following generic reaction: C12H10+nCl2C12H10nCln.+nHCl This reaction results in a mixture of PCB products. The mixture is analyzed by decomposing the PCBs and then precipitating the resulting Cl asAgCl. a. Develop a general equation that relates the average value of n to the mass of a given mixture of PCBs and the mass of AgCl produced. b. A 0.1947-g sample of a commercial PCB yielded 0.4791 g of AgCl. What is the average value of n for this sample?
