| 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

we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the color of the

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

CHEMICAL PARAMETERS OF FRESHWATERS Objectives At the end of this section‚ students should be able to 1. Distinguish between freshwaters and seawater in terms of ionic composition. 2. Describe the variation of ionic composition in natural freshwaters and other inland waters. 3. Explain the factors that contribute to such variation. 4. Describe Gibbs’ model that explains the major factors contributing to variation in chemical composition of inland waters. 5. Explain

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 engineers today face a major dilemma when it comes to deciding what should hold paramount‚ economic gain or moral statute? Many practicing engineers are faced with problems that result from the consequences of their engineering decisions. Engineers have to realize the importance of proper engineering decisions and how one should act when faced with a problem such as deciding what comes first safety or economic gain. When faced with such a problem‚ engineers often employ the risk-benefit

Chemical Warfare Final Draft Do you think it’s right to use chemical toxins to harm or kill people who are defending‚ or fighting for their lives? I don’t and that is why I am aganist chemical warfare. There are other ways which can be used to defend your country without taking away the lives of many people in such a barbaric fashion. Chemical warfare takels many innocent lives even when they haven’t done anything wrong! Chemical warfare is a way of torturing people with nerve‚ blister‚ and choking
