Henry Ford’s Model T was originally designed and built to run on ethanol. Today, ethanol (190-proof alcohol) can be produced with domestic stills for about $0.85 per gallon. When blended with gasoline costing $4.00 per gallon, a 20% ethanol and 80% gasoline mixture costs $3.37 per gallon. Assume fuel consumption at 25 mpg and engine performance in general are not adversely affected with this 20–80 blend (called E20). How much money can be saved for 15,000 miles of driving per year?
There is actually something im confused about, when you calculating V0 for S0=200uM --> V = 0.48*200/ 2.42 + 1 Why are you only using the S0 value=200uM one place in the equation and then using the S0 value from given data the second place in the equation? Shouldnt S0 be 200 uM both places in the equation?
TVA’s Kingston Fossil Plant near Cedarville, Tennessee, burns about 14,000 tons of coal a day. A typical rail car is 53 ft long from coupling to coupling, weighs 30 tons empty and can carry 100 tons of coal. How many minutes would you have to wait at a crossing for this train to pass, each day, if it was pulled by four locomotives, each 70 ft long and moving at 10 miles per hour through town? Such delays cause decreased ability to provide effective emergency response times and interference with commuters and local freight delivery affecting the local economy.

Two-hundred fifty pounds per hour of iron pyrites containing 90% FeS2 and 10% gangue are burned with 20% excess air based on conversion to SO3. The cinder discharged from the burner contains no sulfur. No conversion to SO3 occurs in the burner. The burner gas is passed through a converter which effects a 98% conversion of SO2 to SO3. The converter gas is passed to an absorber where all the SO3 is absorbed by 80% H2SO4 solution, which becomes 100% H2SO4 solution in the process. Establish a basis of one hundred pounds of iron pyrites Calculate: (a) the burner gas analysis, (b) the converter gas analysis, (c) pounds of 100% H2SO4 produced per 24-h day, if waste gas analyzes 0.19% SO2, 4.14% O2 and 95.67% N2
