quest10 : a) (4 pts) You take a balloon filled with a gas mixture on a hot-air balloon trip. The mixture is composed (by mole fraction) of 25% O2 (MM = 32.00 g/mol), 20% Ar (39.95 g/mol), and the remainder of the mixture is composed of 1.75 g of N2 gas (MM = 28.01 g/mol). At departure, the barometer shows a pressure of 1.05 atm and the temperature is 22.0 \deg C. At a maximum altitude of 915 meters, the temperature drops to 8.0 \deg C and the barometer indicates 0.87 atm. The balloon can stretch to a maximum volume of 3.50 L (if the gas volume exceeds this volume, the balloon will burst). Will the balloon burst at the maximum altitude? (Show your work for the calculation of the initial and final volume) b) (2 pts) What is the pressure of each gas at departure (initial altitude)?

Write a Python program that keeps track of a bank account balance. Ask the user for the annual interest rate, the starting balance, and the number of months of which to keep track. Check that each of these is a positive value and allow the user to enter a new value until a positive value is entered (do this for all invalid inputs). A loop should iterate for each month and complete each of the following: Ask the user for the amount deposited into the account that month. Deposit amount should not be negative and should be added to the account balance. Keep a running total of deposit amounts. Ask the user for the amount withdrawn from the account that month. Withdrawal amount should not be negative and should be subtracted from the account balance. Keep a running total of withdrawal amounts. Check for a negative account balance. If balance is negative, exit the loop and print a message for the user stating that the account has been closed due to the negative balance. Calculate the monthly interest using the annual interest rate divided by 12 and multiplied by the account balance. Monthly interest should be added to the account balance after deposits and withdrawals for the month have been added. Keep a running total of interest earned. Print a summary for the month which includes amount deposited, amount withdrawn, interest earned, current balance. After the loop finishes, the program should print the final account balance as well as the deposit, withdrawal, and interest totals; this should complete the program. Remember to display monetary values using a dollar sign and two decimal places.
