Penny-Ante Equilibrium Introduction What is equilibrium? What happens to the amount of reactants and products when equilibrium is reached? What if more reactants or products are added to a system already at equilibrium? In this activity‚ pennies will be used as reactants and products in a reversible reaction to answer these questions and learn more about the fundamental nature of equilibrium. Concepts • Reversible reactions • Equilibrium • Equilibrium constant • LeChatelier’s principle Materials

Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate

Non-users have possibly never tried our product‚ whereas ex-users have but have rejected it. Building awareness of our product to non-users may be necessary. Conversely‚ ex-users are all aware of our product but do not have an affinity for Roaring Fork Beer. Furthermore‚ we must identify whether the reason our product is rejected is sensory or perceptual. The case‚ there is a great deal of supportive evidence that leads us to believe the insight is sensory. Describing the taste as “chemically‚ gassy‚
