2 NaOH(aq) + H2(g) + Cl2(g) If the plant produces 1. five X 106 kg (1500 metric lots) of Cl2 day-by-day, estimate the amounts of H2 and NaOH produced. 116 C HA PTER three Stoichiometry: Calculations with Chemical formulation and Equations three. ninety five The fats saved within the hump of a camel is a resource of either power and water. Calculate the mass of HzO produced via metabolism of one. zero kg of fats, assuming the fats is composed fullyyt of tristearin (C57H11006), a standard animal fats, and assuming that in metabolism, tristearin reacts with ounces to shape merely COz and HzO. [3. ninety six] whilst hydrocarbons are burned in a constrained quantity of air, either CO and COz shape. whilst zero. 450 g of a specific hydrocarbon used to be burned in air, zero. 467 g of CO, zero. 733 g of CO:u and zero. 450 g of HzO have been shaped. (a) what's the em­ pirical formulation of the compound? (b) what percentage grams of ounces have been utilized in the response? (c) what percentage grams could were required for whole combustion? three. ninety seven a mix of Nz(g) and Hz(g) reacts in a closed box to shape ammonia, NH3(g). The response ceases earlier than ei­ ther reactant has been completely fed on. At this degree three. zero mol Nz, three. zero mol Hz, and three. zero mol NH3 are current. what number moles of Nz and Hz have been current initially? [3. ninety eight] a mix containing KC103, KzC03, KHC03, and KCl was once heated, generating CO:u ounces, and HzO gases accord­ ing to the subsequent equations: 2 KC103(s) -> 2 KHC03(s) -> 2 KCl(s) + three Oz(g) KzO(s) + HzO(g) KzC03(s) -> KzO(s) + COz(g) + 2 COz(g) The KCl doesn't react lower than the stipulations of the reac­ tion. If a hundred. zero g of the combination produces 1. eighty g of HzO, thirteen. 20 g of COz, and four. 00 g of oz., what used to be the composi­ tion of the unique blend? (Assume entire decom­ place of the aggregate. ) three. ninety nine whilst a mix of 10. zero g of acetylene (CzHz) and 10. zero g of oxygen (Oz) is ignited, the ensuing combustion reac­ tion produces COz and HzO. (a) Write the balanced chemical equation for this response. (b) that's the lim­ iting reactant? (c) what percentage grams of CzHz, 02, CO:u and HzO are current after the response is entire? three. a hundred Aspirin (C9H804) is made from salicylic acid (C7H603) and acetic anhydride (C4H603): C7H603 + C4H603 -> CgHs04 + HCzH Pz (a) How a lot salicylic acid is needed to provide 1. five x 10z kg of aspirin, assuming that each one of the salicylic acid is switched over to aspirin? (b) How a lot salicylic acid will be required if in basic terms eighty% of the salicylic acid is switched over to aspirin? (c) what's the theoretical yield of aspirin if 185 kg of salicylic acid is permitted to react with one hundred twenty five kg of acetic anhydride?
