CHEM 3216 Written Midterm 3 (Fall 2023)

Provided are spectra for a compound with molecular formula CgH100 Part A) Give the degrees of unsaturation Part B) Identify the peaks that are associated with specific bonds of the structure and list the corresponding functional groups that the specific bonds belong to. Re- create the example table below that organizes this information. Use the wavenumbers that are already labeled on the spectra. Example table: wavenumber (cm-1) Corresponding Bond Type Corresponding Functional Group C(sp3)-H N-H 2978 3300 Part C) Draw the structure and clearly indicate which hydrogens correspond to which signals in the HNMR spectrum ONLY. The signals are already labeled A-D on the HNMR spectrum. Match the hydrogen labeling (HA, HB, etc.) on your drawn structure to the signal labeling provided. 4300 3320-2872 2951 3006 3003 2001 alkyl amine 1613 1510 1000

Please help with questions 2-3

Im just on 6th grade pls answer the question simple. Thank u so much hope u could help me thank you ❤❤❤❤

help  please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working!

As you work on the questions, have your lab manual and text book handy. If you have questions go to one of the office hours and remember, do not leave it for the last minute! In the titration of 25.00 mL of a water sample, it took 19.090 mL of 3.165x 10-3 M EDTA solution to reach the endpoint. Calculate the number of moles of EDTA required to titrate the water sample. (enter your answer with 3 significant figures) 6.04x10-5 You are correct. Your receipt no. is 151-9969 ? Previous Tries The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample titrated. (enter your answer with 3 significant figures) 6.04x10-5 You are…

26) The floor tiles in SE 27 are about 1 square foot and the lab is about 25 tiles wide and about 36 tiles from front to back. When the emergency shower was demonstrated, in 10. seconds the water in the trash can was about 1 foot deep. One student estimated this was 2.5 gallons. Estimate how deep the room will get in inches after a 15 minute shower.

To run a spectrophotometry experiment, begin by warming up the spectrophotometer and preparing the samples. Be sure to select the correct absorbance (X), then run a measurement on the sample solution. Follow up by running measurements on sample solutions. Once data is collected, turn off the instrument, clean the area, and discard the samples. Partially correct (2 of 4 correct)

Based on the information given, identify the most significant error in the preparation of Graph 2.     A)  The title appears in a font which is too small.   B)  The best-fit line does not intersect any data point.   C)  There is wasted space on the graph.   D)  The x-axis scale divisions are uneven.

Current Attempt in Progress From the curves shown in Animated Figure and using the following Equation, determine the rate of recrystallization for pure copper at the several temperatures. Make a plot of In(rate) versus the reciprocal of temperature (in K-1). (a) Determine the activation energy for this recrystallization process. (See Section FACTORS THAT INFLUENCE DIFFUSION.) (b) By extrapolation, estimate the length of time required for 50% recrystallization at room temperature, 20°C (293 K). (a) i kJ/mol (b) i days

Listed in the Item Bank are key terms and expressions, each of which is associated with one of the columns. Drag and drop each item into the correct column. Order does not matter. Terms Extrinsic properties (also called extensive) are directly related to the amount of material being measured. Intrinsic properties (also called intensive) are those which are independent of the amount of matter present.
