Fuels for motor vehicles other than gasoline are being eyed because they generate lower levels of pollutants than does gasoline. Compressed propane has been suggested as a source of economic power for vehicles. Suppose that in a test 20 lb of C3H8 is burned with 400 lb of air to produce 44 lb of CO2 and 12 lb of CO. What was the percent excess air?

2. You are working for a power plant that makes use of coal tar, a type of liquid fuel as its raw material for burning in a boller. This type of fuel is mainly composed of carbolic oll, naphthalene oil, creosote oil and anthracene oll. After analyzing coal tar you were able to wow it contalns 85.9% 0,63% H, 2.2% S. 4.5% O and 1.1% N. You told the operators to make use of excess air for combustion. The air was assumed to enter at 30°C with 90%RH. In order to follow DENR regulations, you took a sample of the bumper gis to analyze its contents.   Midway your experimentation, the equipment you used broke so it only gave you a partial analysis of 10.64% CO, 3.19%, CO and 0.64% H. a. The operators had no idea how much excess alr was needed, What do you tell them? b. You need to make the report to be passed that day for the analysis of the burner gas. What analysis will you submit the volume of the bumer gas in m/ka tuel is aso needed in your report c. The alr to be supplied a controlled…

Using RCRA procedures, determine if the following are hazardous wastes. State the reason why, or why not it is hazardous. If it is hazardous, state the category number. Assume the industry producing the waste is a RCRA hazardous waste generator. 1. A drum of sulfuric acid at pH 1.2. A drum of waste trichloroethylene (22% by volume).

A sample of sucrose, C12H22O11, is contaminated by sodium chloride. When the contaminated sample is burned in a bomb calorimeter, sodium chloride does not burn. What is the percentage of sucrose in the sample if a temperature increase of 1.50°C is observed when 3.000 g of the sample is burned in the calorimeter? Sucrose gives off 5.64×103 kJ/mol when burned. The heat capacity of the calorimeter and water is 22.51 kJ/°C. _____________ %
