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-

because 2+1 integration was overlapping). The multiplicities of all signal clusters of H1 spectrum helped in determining the structure of compound. The signal at 4.9 indicates that the alkane group must be attached with electronegative compound that shifted alkane group by “2”‚ and the signal at 2 indicate the alkane group must be attached with carbonyl group. Thus‚ all the information collected from NMR suggested that the product of fisher esterification was (1‚3-dimthylbutyl) acetate. A number

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

There are many unexplainable things that happen to man different people in this world and now they have explanations. Miscarriages are accruing more and more often these days. There are many logical reasons for the occurrences of miscarriages. There has been a great deal of research concerning miscarriages and now we came prevent these from happening. Doctors have discovered that caffeine plays a big part in miscarriages today. Smoking also is a leading cause of miscarriages in today’s studies. Studies

water would be another challenge. 8. Is the water treated prior to its discharge? If so‚ with what? Sodium hypochlorite (bleach solution) is used to kill remaning organisms in the water grom the final settling tanks. The second stage is water DE chlorination‚ this is where chemical (sodium bisulfite) is used to neutralize the bleach prior to the clean water discharge. 9. Where is the treatment water discharged? Potomac River 10. Who monitors the discharge of treated effluent to ensure that it meets
