answer

Select all the statements that are correct given the information/content of the ldentifying Plastics by Density Infographic. M) The neutral buoyancy test procedure does not require NANOpure water, ~ as only ethanol and/or saturated (5 M) sodium chloride solution is/are used. M) The neutral buoyancy test procedure for an identification should be performed ~ on three (3) fragments of isolated/collected assigned UNKNOWN plastic fragments that appear to be of the same type. M) A neutral buoyancy determination on PETE fragments will work with the ~ available resources, since PETE has a density of 1.3 - 1.4 g/mL and will sink in saturated (5 M) sodium chloride (which has a density of 1.2 g/mL). M) For a neutral buoyancy test, small plastic fragments are better behaved, large ~ fragments can prove very challenging, and "chains" of fragments are nearly impossible to work with and should be cut apart into free fragments. |:] The neutral buoyancy test procedure is carried out in 20 mL vials
