16. The combustion of gasoline (octane) in a car engine can be represented by the following equation: 2C3H18(1) + 2502(g) a. What mass of oxygen is used up to burn a full tank of 36.00 kg of gasoline? Text --> 16CO2(g) +18H20(g) b. Why might a vehicle that is calibrated to run perfectly at sea level run poorly at higher elevations? Text Тext According to the Canadian Automobile Association, the average Canadian drives 20,000 km/yr. C. Assuming that distance, how many more kg of carbon dioxide are added to the atmosphere each year by a Toyota Tacoma (fuel economy of 12.8 L/100 km) than a Toyota Prius (4.52 L/100 km)? The density of gasoline is 0.719 kg/L.

OSHA's Hazard Communication Standard requires chemical manufacturers to evaluate hazards relating to their products and provide a Safety Data Sheet in accordance to the Globally Harmonized System (GHS) in which the use of pictograms (see Figure 1) is required to communicate hazard information. Predict (with reasons) two (2) hazards related to each of the two activities below, and assign two (2) relevant pictograms listed in Figure 1 to each of the two activities. Activity 1: Removing diethyl ether (last opened in 2019) using a rotary evaporator. Activity 2: Using carbon monoxide gas as a reducing agent to reduce iron chloride. Figure 1. Pictograms advised by the Globally Harmonized System for communication of chemical hazards.

7. The crude oil is fed to a washing unit and in this unit it is mixed with fresh water fed to the washing unit. Crude oil contains salt and oil. There are two exit streams from washing unit. The first stream is the oil stream. The oil stream contains 5% salt but not water. The second stream is "spent wash water" stream. This stream contains 15% salt and the balance water. The mass ratio of crude oil to fresh water used is 4:1. All compositions are given on mass basis. a) Draw and label a flowchart to this process b) Do the degree of freedom analysis. Prove that for an assumed basis of calculation, flow rate and compositions of all process streams can be calculated from the given information. c) Calculate flow rate and compositions of all process streams for 100 kg of oil stream taken as product.

Acrylonitrile and water are produced from propene, ammonia, and oxygen in a 2 L vessel by the following reaction: C3H6 + NH3 + O2   →→    CH2CHCN + H2O If 27.6 moles of H2O is produced in 5-min.  What mass of propene  in Kg (kg) is consumed in 30-min. Assume Molar Weight of propene = 42.08 g/mL

A certain mineral contains the substance Cu(NO3)2 .Cu2SO4. Cu3N2. The copper present in a 1.5000g sample of this mineral is analyzed by adding aqueous ammonia to precipitate the copper as Cu(OH)2 and then incinerated and weighed as CuO. What is the weight percentage of Cu in this mineral if 0.85g of CuO were obtained? Please answer fast I give you upvote.

Here is a use objective for a chemical analysis to be performed at a drinking water purification plant: “Data and results collected quarterly shall be used to determine whether the concentrations of haloacetates in the treated water demonstrate compliance with the levels set by the Stage 1 Disinfection By-products Rule using Method 552.2” (a specification that sets precision, accuracy, and other requirements). Which one of the following questions best summarizes the meaning of the use objective?(i) Are haloacetate concentrations known within specified precision and accuracy?(ii) Are any haloacetates detectable in the water?(iii) Do any haloacetate concentrations exceed the regulatory limit?
