- A typical formulation for window glass is 75% SiO₂, 15% Na₂O, and 10.% CaO by mass. What masses of sand (SiO₂),sodium carbonate, and calcium carbonate must be combined toproduce 1.00 kg of glass after carbon dioxide is driven off bythermal decomposition of the carbonates?A commercial 737 jet transporting 143 passengers and 5 crew members from Kansas city (MCI) to Baltimore (BWI) burned 11800 lb. of Jet A fuel. Jet A fuel is kerosene based, consisting primarily of CnH2n+2 hydrocarbons, with n = 6 to 16, so the Carbon:Hydrogen ratio is close to 1:2. During this flight , how much CO2 (in kg) was released into the atmosphere? (assume the combustion of fuel was complete, so all fuel was converted into H2O and CO2).0.004 C8H7NO3, 15mL ethanol, 0.002mol NaBH4 was used. HCl was used to acidify. It was then extracted with ether. Then it was dried and a mass of 0.32g was obtained. What is the balanced equation of this synthesis, and what is the limiting reagent?
- One of the sources of iron is magnetite, Fe3O4 (FeO and Fe2O3 mixed), which reacts with coke (carbon) to produce iron in the liquid state and carbon monoxide. If we assume that coke is pure carbon, how much is supplied to produce 10,000 metric tons of iron?Urea, CH4N2O, is produced by the reaction between ammonia and carbon dioxide, as shown by the followingequation. 2NH3 + CO2 → CH4N2O + H2O a. Calculate the quantities, in kilograms, of NH3 and CO2 that should combine to produce 6.0 kg of urea.NH3 _______________ kgCO2 _______________ kg b. How many kilograms of water will be produced as the side product in this process?H2O _______________ kg42. The primary use of 1,2‐dichloroethane, ClCH2CH2Cl, is to make vinyl chloride, which is then converted into polyvinyl chloride (PVC) for many purposes, including plastic pipes.

- Ammonia (NH3) is naturally produced through the decomposition of organic material as wellas being high in wastewater discharged to natural waters. In the environment it is oxidizedto form nitrite (NO2-), and nitrite is then oxidized to form nitrate (NO3-) in a process callednitrification. The balanced equations are given below:2NH3 + 3O2 → 2NO2- + 2H+ + 2H202NO2- + O2 → 2NO3-a) Assuming complete oxidation, what is the theoretical oxygen demand to convert100mg/L of ammonia to nitrate (i.e., how much oxygen is necessary)? Report youranswer as mg/L of O2.Answer: 376 mg/L O2b) This conversion process makes water more acidic. With reference to the equations forpH, explain why this occursThe sugar glucose (C6H12O6) is broken down in a decomposition reaction to ethanol (C2H6O) and bubbles, CO2.
