Determine the identity of a cube of metal that measures 1.5 cm on each side and has a mass of 35.45 g

volume of cube is 1.5^3 = 3.375 cubic cm

divide mass by volume to get density

35.45/3.375 = 10.50 grams

 now find the metal that has a density of 10.5 grams

 not sure if you have a chart that lists them or not

 Silver has a density of 10.5

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

an energy transformation flow diagram is shown

where is it ?
