Question 2 of 22 This question is designed to ensure that you are using your calculator correctly. Use a calculator to do these calculations. Keep at least two significant figures in your answers. 1.6 x 104 %D 8.6 x 10-2 TOOLS x10

Choose the selection which most accurately gives both the value of the angle numbered 1 and the value of the angle numbered 2 in the figure above. Choose the best possible (most specific) answer. Other answers will be graded wrong. For example, if an angle is somewhat greater than 109.5 degrees, an answer which says that it is somewhat less than 120 degrees, while somewhat correct, will be graded wrong. a) Angle 1 is very close to 180 degrees and angle 2 is very close to 90 degrees. b) Angle 1 is somewhat less than 109.5 degrees and angle 2 is somewhat less than 109.5 degrees. c) Angle 1 is somewhat less than 109.5 degrees and angle 2 is very close to 90 degrees. d) Angle 1 is somewhat less than 109.5 degrees and angle 2 is somewhat less than 120 degrees. e) Angle 1 is somewhat more than 109.5 degrees and angle 2 is somewhat less than 109.5 degrees.

Pmease assist with number 1.   this is NOT a graded question.  See below: This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

Name the following Fe(NO3)2

(number 15, for the second picture)

Rank the values according to magnitude. Please see screenhot. Can someone help me understand this?

Please answer question number 2  correctly with the correct answer. there is a picture of an example of a ''Dimensional analysis Format' below. please write out all work showing the math in dimensional analysis format. (please show all work)   Question 3: What is the molar mass of each of the following compounds?   A. C6H12O6   B. NaHCO3

Significant Figures of log measurements. Perform the following calculations and report each answer with the correct number of significant figures Log 4.38 pH = – Log 6.243 x 10-5; pH = ______. Antilog -1.48 Antilog 32.23 Perform the following calculations and report each answer with the correct number of significant figures (321.54 x 79.2)+0.0056 log 8.005 x 10-4 + log 6.0455 x 10-7 (5.6x103 x 2.42x105)/(0.359+0.699)
