- 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.Foundation Of College Chemistry can you please give me the answer step by step How many significant figues should the answer in each of these calculations contain?

The transmission electron microscope (TEM) image shows gold nanoparticles (bright white) that have been coated with silica (SiO2 - not as bright). The scale bar in the lower right of the image corresponds to 40.0 nm. Assume that the gold nanoparticles are spherical and have a diameter of 10.0 nm. Answer the following questions. What is the volume of a single Au particle. What is the mass of the particle (look up the density for gold). If the initial solution that was used to synthesize the gold particles contained 50.0 mL of 1.00% (w/vol) Au, how many particles can you synthesize? If the diameter increases by 10%, what % change will occur in the number of particles made?
