Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

In other words‚ it simplifies to the idea of ‘an eye for an eye’ (Heim‚ 281). To this day‚ castration or even chemical castration is still used in parts of America and some European countries around the world but the question of its effectiveness remains. One can argue‚ castration removes the sexual drive of the offender but it simply cannot cleanse their state of mind‚ “Chemical castration assumes that sexual offenders‚ after losing their sexual drive‚ will stop molesting. Anyone who has taken

classes of chemical messengers. The human body contains chemical messengers. There are four groups of chemical messengers within the human body. Each chemical messenger are unique in their own way‚ having different functions throughout the body. The four groups are as follows in no specific order: Autocrine‚ paracrine‚ neurotransmitter‚ and endocrine. Neurotransmitter chemical messengers are let out by neurons where they are deposited into the synaptic cleft. Neurotransmitter chemical messenger

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose

Oscillating chemical reaction Aim: The overall reaction rate and concentrations of some reaction intermediates of certain chemical reactions oscillate‚ even in a homogeneous system. This phenomenon is commonly found in living organisms. These periodical variations occur when a feedback mechanism is available in which a product changes the reaction rate. In this experiment will produce oscillations in both time and space in the concentrations of cerium(IV) and cerium(III) in the BZ reaction. Use the
