(TCOs 2,4, 5, and 8) Write a program to input a purchase amount and calculate the sales tax and total due. The sales tax depends on the county identifying code. Counties with a number less than 20 have a 5% sales tax. The 21-35 codes have a sales tax of 6%. Codes above 35 have a sales tax of 7%. The purchase amount and county code are entered by the user. Use a loop to validate that the county code is between 10 and 40. Display the amount of the sales tax and the total.
The heat of formation of Al2O3(s) is change Hf= -1669kJ/ /mol. a.) Calculate the heat evolved when 3.47 g of Al burns in oxygen. b.) Find the mass in grams of Al that burns when 1039 kJ are evolved.
Calculate the final pH when 2.6 mmole NaOH is added to 1 mmole phosphoric acid, given pKa1 = 2.1, pKa2 = 7.2 and pKa3 = 12.4
To produce a device isolation trench you first use CVD to deposit an oxide of 50nm on Si(100). You follow that by a dry thermal oxidation at 1000C for 30 min. At last you fill the rest of the trenches with a CVD Si3N4 layer. a) Explain what is the..
The decomposition reaction given below: 2 NH3(g) 1 N2(g) + 3 H2(g) is carried out in a closed reaction vessel. If the partial pressure of NH3(g) is decreasing at the rate of 131 torr/min, what is the rate of change of the total pressure in the ves..
Calculate the potential of the following cell and indicate whether the reaction is expected to be spontaneous. Cr + 3 Ag+ ---> Cr3+ + 3Ag
Using the data shown in the table, calculate the pressure exerted by 1.00 moles of CO2 confined in a volume of 3.00 L at 450. K. Compare the pressure with that predicted by the ideal gas equation
Calculate the molar concentration of OH - ions in an 1.43 M solution of hypobromite ion, BrO- (Kb = 4.0 10-6).
Write the rate law for the clock reaction (equation 1) using variable for exponents.
Question- Nitrogen and oxygen do not react appreciably at room temperature, as illustrated by our atmosphere. But at high temperatures, the reaction below can proceed to a measurable extent.
how does direct current break apart water molecule? Does the DC current fill the outer shell full of electrons making a weaker attraction so hydrogen seperates from oxygen?
Methanol, ethanol, and n-propanol are three common alcohols. When 5.00 g of each of these alcohols is burned in air, heat is liberated. Calculate the heats of combustion of these alcohols in kJ/mol.
A lightning flash is seen and then 1.9 seconds later the thunderclap is heard. How far away in miles did the lightning strike if sound travels 1087 feet per second and a mile is exactly 5280 feet
