These spectra are from the set of seven compounds from the pre-lab for this experiment: acetanilide, acetic anhydride, acetone, benzoic acid, caffeine, ethyl-4-aminobenzoate, and ethyl acetate. for each spectrum list the wavenumber of any carbonyl (c=o) stretch present and identify the molecule. give a brief (one sentence) explanation for your choice. one compound will not be used.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
