Chemical properties Chemical properties describe the characteristic ability of a substance to react to form new substances. Physical properties Physical properties are characteristics that can be measured without changing the composition of the sample under study Elements contain only one type of atom Mixtures contain more than one type of molecule Compounds Contain more than one type of atom, but only one type of molecule Heterogeneous Mixtures mixtures that are not uniform and so di...

The cross section for scattering a certain nuclear particle by a co pper nucleus is 2.0 barns (if needed, look up the definition of a barn). If 109 of these particles are fired through a copper foil of thickness 10 μm, how many particles are scattered? (Copper’s density is 8.9 g/cm3 and its atomic mass is 63.5). 2. The differential scattering cross section for 6....
