Observation of Chemical Changes Purpose In this experiment‚ the student studied the composition of materials in a setting where the indications of chemical changes were safely observed. The changes observed consisted of bubble formation‚ colors‚ viscosity‚ and precipitate formation. Procedure Using a well plate: use a different well for each chemical combination. Two drops (unless otherwise noted) of each chemical in the combinations (below) should be placed in one well. A dark and light

Chemical Properties of Egg Tempera Art is traditionally viewed as a creative process far removed from science. However‚ beyond the imaginative efforts that contribute to the creation of a work of art are the physical materials that are used as the medium. While science is not an essential part of the thought and design process‚ an understanding of the chemical properties of different art media is integral to creating a work of art that will not only match the artist’s vision but will also stand

Chemical Eric: Dealing with the Disintegration of Central Control Part 1: 1. What hormonal problem could be causing these symptoms? Eric’s symptoms include: large hands and feet‚ low thyroid activity‚ low cortisone levels‚ low testosterone levels‚ high growth hormone levels‚ and swelling in his right knee. Since most of Eric’s symptoms are hormonal‚ he is clearly having an endocrine gland problem. Cortisone‚ testosterone‚ and growth hormone levels are being affected‚ it is likely that he his having

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

Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

| 1. For Part 2: Single-Displacement Reactions: For each of the four single-displacement reactions‚ describe what happened in each well. If a chemical reaction occurred‚ write a balanced equation for it. Then using the A‚ B symbols‚ write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 • aluminum – Al copper sulfate – CuSO4 • zinc
