The program should be written in MIPS. Develop a Make-Change program. Accept any number from 1 to 99 cents and determine the least number of coins (quarter, dime, nickel, and pennies) which can be used to make up that total value and print out the results in a tabular format. You do not have 2) any half-dollars, 3) any quarters, 4) any dimes, or 5) any nickels. (but lots of pennies)

Q7;

Part A

1. Draw the Lewis dot structure for HNO₂.
2. Based on your drawing what is the hybridization of the molecule.
3. What is the bond angle?
4. Give the molecular geometry.
5. What type of bond is formed between nitrogen and hydrogen and each oxygen? Explain your reasoning.
6. Is the molecule ionic, nonpolar covalent, or polar covalent. Justify your answer.

Part B

1. The nitrate ion (NO₃^1-) bonds are all the same length but are longer than the bonds for the nitrite ion (NO₂^1-). Based upon Lewis dot structures give an explanation for the difference.
2. Justify your Lewis dot structure for the nitrite ion with a formal charge calculation.
3. What is the molecular geometry for the nitrate and nitrite ions?
4. For nitrate how many sigma and pi bonds are in a single molecule?
