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?
A student performed the first determination in Part 2. They reacted 59.11 g of 1 M HCl with 0.7347 g of magnesium oxide.

A 120. MW coal plant wants to add a SOXemissions control system to reduce its emissions. The emission control system has a capitalcost of $815 per kW and reduces SOX emissions by 98% to 0.0918 kg/MWh. Assume thelifetime of the emission control system is 20 years and the power plant produces 650GWh/y. a)What is the annualized cost of this system in dollars per year if the discount rate (interestrate) is 7.0 percent/year? What if the discount rate is 4.0 percent/year? b)What is the cost per 1.0399 x 104 kWh of electricity usage (the average annual U.S.residential electricity consumption in 2017 according to the EIA) at each of the discountrates specified in part a? c)What is the cost per metric ton of SOx removed at each of the discount rates specified inpart a?
