Awater sample consists of the following cadmium species and their percentages of the total cadmium concentration: cd2 (36 %); cdhco3- (14 %); cdcl- (25 %); and cd(oh)2 (25 %). what percentage of cd is toxic to aquatic organisms

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Water's surface tension and heat storage capacity are accounted for by its a) orbitals b) weight c) hydrogen bonds d) mass e) size

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
