1 PRACTICE EXAM (not all questions pertain to a specific mid-term). This is taken from an earlier final exam. 1. (4 pts) Permanganate ion oxidizes sulfide ion to elemental sulfur (which you should represent as a single S atom) and is reduced to MnO2 in basic solution. In the balanced equation for this reaction‚ which you should determine in the work area‚ how many water molecules and hydroxide ions are needed in the final balanced equation? Work area: # of H2O ____4______ # of OH-

simply failed at throughly understanding how much the University of Colorado Boulder meant to me. That might sound corny‚ but when you grew up coming to every sporting event your dad could take you to‚ you fall in love with CU pretty easily. I had always said I would go to CU‚ that was the dream. As time passed‚ and senior year rolled around I felt the need for change. I wanted to be different from the rest of my family‚ and forge my own unique path in life. August came‚ I packed up my possessions

agricultural‚ commercial and industrial waste] as adsorbents for pollution abatement have been investigated extensively in recent years. The non conventional adsorbents process remarkable adsorption capacity for the removal of heavy metals like Cd‚ Cr‚ Cu‚ Fe‚ Hg‚ Mn‚ Ni and Pb‚ surfactants‚ dyes‚ colour‚ organics from the industrial and municipal effluent. This paper represents the review of past work on removal of heavy metals by biosorption by using low cost adsorbents in natural and modified forms

reactant breaks down into multiple products (i.e. 2KCl (S) 2K (s) + Cl2 (g)). Single displacement reactions occur when one more active element kicks out or displaces another less active element in a compound (i.e. Zn (s) + CuSO4 (aq) ZnSO4 (aq) + Cu (s)). Double displacement are similar to single displacement reactions however two elements are displaced instead (they switch compounds‚ observe: KCl (aq) + AgNO3 (aq) AgCl (s) + KNO3 (aq)). A neutralization reaction double displacement reaction
