Written Response/Drawing Questions Written Response/Drawing Questions Instructions Questions 2 through 5 of Exam 1 require handwritten responses and/or drawings. Before you began this exam, you should have either printed the CHEM 210 Exam 1 Answer Sheet or copied the information from the answer sheet onto your own scrap paper. You may use either option during the exam. If you did not print the Exam 1 Answer Sheet or copy the information onto your own paper before the exam began, you will need to use blank scrap paper. You will not be able to print the answer sheet during the exam. If you use blank scrap paper, make sure each answer is clearly numbered so it matches the correct exam question. For Questions 2 through 5, write or draw your responses by hand on the Exam 1 Answer Sheet or on your own paper. After you complete each written response or drawing, hold your work up to your webcam so it is visible in the exam recording. After you complete Question 5, continue with the remaining questions in Canvas. When you have finished and submitted the Canvas exam, you will have 5 minutes to upload your handwritten response/drawing answers to the Exam 1 Written Response/Drawing Assignment in Canvas. Your uploaded file must clearly show your work for Questions 2 through 5. Make sure the image or scan is readable before submitting it.

Assign all non-zero formal charges to the non-hydrogen atoms in the module below. All lone pairs have been drawn in.  Click to Show Image Description The image shows a one-carbon structure. A carbon atom is single-bonded to three hydrogen atoms: one above, one to the left, and one below. The carbon is also single-bonded to an oxygen atom on the right. The oxygen atom has three lone pairs shown as pairs of dots around it. The letters “Na” appear to the right of the oxygen atom. O [O] Na [Na] C [C]

On the answer sheet provided to you for the exam, or scrap paper, complete the following three part question: (9 pts) Draw one valid Lewis structure for each compound. Assign formal charges to atoms if necessary.      N2H4      NaN3      HCONH2

If you violate any of these policies, you may not receive any credit for the test or be required to take a make-up test. You must hold up the cheat sheet (both sides) in front of the camera before you begin the test to receive credit. Take the test in a quiet, private space free of background noise, sitting at a desk or table (not on a bed, couch, or in a car). Ensure no people (especially children) or pets are present and avoid bright backgrounds such as windows or lights behind you. You may not leave the room during the test. Ensure your webcam and microphone work and stay on (microphone unmuted). FRONT CAMERA: Keep your full face and upper body visible on camera throughout the test. SIDE CAMERA: Your setup should resemble the example shown in the photo below with the green check mark. You must make sure your profile, including your nose, one eye, and your mouth, is clearly visible at all times. Both hands, keyboard, screen, and any permitted materials must also remain visible throughout the test. Avoid having a window directly in view of the camera, as it will make you and the workspace harder to see and could cause errors during the test. During the Test Use only one computer for the test. Disconnect and power off all other devices, including cell phones, extra monitors, screens, tablets, iPads, smartwatches, and any similar electronic devices/technology as their use is prohibited. Use of any AI tools (e.g., ChatGPT, Claude, Gemini, Canva, Perplexity, GitHub Copilot) is strictly prohibited. Do not open other websites, apps, or communication tools (e.g., Teams, Google, ChatGPT, etc.). Taking photos, screenshots, or sharing test questions during or after the test is strictly forbidden. You may not read aloud questions or the answer choices. Remain seated and still; leaving camera view or excessive movement may be flagged.

Gregor has written code containing subroutines in assembly language. He uses a stack as a communication area for passing parameters and getting return values when calling the assembly language subroutines. However, his self-defined convention does not contain any guidance on register usage. Which of the following could directly result from him not strictly adhering to any register usage convention?

For the variables defined below, show how a compiler would pack the data starting from memory address 1000.  Pack in such a way that each variable is sequentially allocated in memory and naturally aligned to its data type while otherwise using as little memory as possible The compiler will NOT automatically reorder variables  For bytes that are inserted for natural alignment purposes, write in “pad”. Assume a 32-bit little-endian byte-addressable architecture. int a = 0x55443322;char b = 0xFF;char c[] = {0x1B, 0x2C};short d = 0x9988;int e = 0xAABBCCDD; For any cell that might require padding type “pad” as your answer. Do not include 0x in your answers. +3 +2 +1 +0 Address (Decimal) 0x[a4] 0x[a3] 0x[a2] 0x[a1] 1000 0x[pad1] 0x[c2] 0x[c1] 0x[b1] 1004 0x[pad3] 0x[pad2] 0x[d2] 0x[d1] 1008 0x[e4] 0x[e3] 0x[e2] 0x[e1] 1012
