Chromium (Cr) is a metal that is added to steelto improve its resistance to corrosion (for example, to make stainless steel). Calculate both the number of moles in a sample of chromium
containing 3.04 X 10^18 atoms and the mass of the sample.

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
