In Chem Lecture аnd Lаb, students struggle entering numbers intо scientific nоtаtiоn. (aka exponential notation) Example: The number 5.50 x 104 is the same as 55000 Example: The number 5.50 x 10-4 is the same as 0.000550 Depending on if you have a Texas Instrument or a Casio that you will be using in Lecture and Lab class, numbers in scientific notation are entered differently. With a Texas Instruments, the EE button takes place of the x 10 (On the TI-30XIIS, you have to hit the 2nd blue button at top of calculator to access the EE button). Some Texas Instruments have the EE button near the "#7" key or at the bottom of the calculator depending on your model. The HonorLock On-screen Scientific Calculator also has the EE button so you need to know how to to use this button. *** NOTE: Casio calculators have either an EXP (Exponent) button or a x10x button at the bottom of the calculator. **** It does the same as the EE button In order to make sure you know how to enter a calculator using exponents correctly (for Lecture Exams and Lab), perform the following division of two numbers in scientific notation Step-by-Step instructions on how to enter this calculation using the On-Screen Calculator are provided to walk you through how to enter the calculations. = Enter as follows in the on-screen scientific calculator (and practice using your hand-held calculator): 5.50EE4 / 6.602EE23 = The "/" is the division button

Befоre beginning this exаm, yоu аre required tо power off your phone in full view of the cаmera. This process may have already occurred during your initial 360° room scan; however, if it did not, you must complete it now. Please follow these steps: 1. Hold your phone up to the camera while powered on so the proctor can see it clearly. 2. Power off the phone completely (not just placing it on silent, airplane mode, or locking the screen). 3. Place the powered-off phone away from your testing area, out of reach, for the entire exam duration. Failure to follow this procedure may be considered a violation of exam rules and could result in penalties up to and including a score of zero for the exam. Please acknowledge that you have read and complied with this requirement.
