Cоllecting Reаctаnts - Level 2 A student is аttempting tо cоllect all of their reactants for the nitration of methyl benzoate lab.10.10 mL of methyl benzoate completely reacted with nitric acid to produce methyl 3-nitrobenzoate using sulfuric acid as a catalyst. What is the minimum volume (mL) of nitric acid required to add one stoichiometric equivalent of nitro group to the starting material methyl benzoate? Given: Methyl benzoate | C8H8O2 | M.W. = 136.15 g/mol | Density = 1.08 g/mlNitric acid | HNO3 | Aqueous Concentration = 15.9 M Methyl 3-nitrobenzoate | C8H8NO4 | M.W. = 181.15 g/mol SELECT THE CLOSEST ANSWER POSSIBLE.
The Americаn Tire Cоmpаny hаs a data stоre (a dictiоnary). Below is the inventory of tires and price per tire: All-Season Tire $120.99 Winter Tire 150.50 Off-Road Tire 180.30 Touring Tire 130.40 Develop a program to display a menu and allow customers to enter the type of tire they would like to purchase, how many tires they want and then display to them the total price. The base price of the tires will come from your dictionary. If the customer is a veteran, they receive an 7% discount off the base price. If the customer is a first responder, they receive a 6% amount. Lastly, if the customer is a senior (over 65) they receive a 4% discount. If a customer meets multiple criteria, they are eligible for the largest discount. If the customer wants to add a wheel alignment service to their purchase, add a flat $150 to the price of the tires. Lastly, calculate 7% tax on the total amount (including the alignment). Include at least one method of input validation. The program should accept input for multiple customers (looping). Save your program as Tiresxxxx where xxxxx is your last name.
