Zinc in its 2+ oxidation state is an essential metal ion for life. Zn2+ is found bound to many proteins that are involved in biological processes, but unfortunately Zn2+ is hard to detect by common chemical methods. Therefore, scientists who are interested in studying Zn2+- containing proteins will frequently substitute Cd2+ for Zn2+ since Cd2+ is easier to detect. Based on the properties from this chapter and their positions in the periodic tables, provide one pro and one con of using Cd2+ as a Zn2+ substitute?
You and a partner are asked to complete a lab entitled“Oxides of Ruthenium” that is scheduled to extend over twolab periods. The first lab, which is to be completed by yourpartner, is devoted to carrying out compositional analysis.In the second lab, you are to determine melting points. Upongoing to lab you find two unlabeled vials, one containinga soft yellow substance and the other a black powder. Youalso find the following notes in your partner’s notebook—Compound 1: 76.0% Ru and 24.0% O (by mass), Compound2: 61.2% Ru and 38.8% O (by mass). (a) What is the empiricalformula for Compound 1? (b) What is the empiricalformula for Compound 2? Upon determining the meltingpoints of these two compounds, you find that the yellowcompound melts at 25 °C, while the black powder does notmelt up to the maximum temperature of your apparatus,1200 °C.
