CEM 142 Exam 3 MSU Questions and Answers Rated A+ What do you know about reactions? (make a list) -Atoms are conserved. They are only re- arranged. -Properties of products are emergent (not a mixture of the reactants properties). -Reactions can be classified by the type of reaction (how it occurs). -Reactions are always accompanied by an energy change (can be exo and endo) that results from changed in interactions (bonds and IMFs) in the reactants and products. -Reactions are alway...

What is an acid? - Answer-solution has an excess of H+ ions What is a base? - Answer-solution has an excess of hydroxyl ions (OH-) What is neutralization? - Answer--process where acid and base are mixed until they become neutral and the PH is 7. What are the two products of a neutralization chemical reaction? - Answer-water and salt ( The type of salt depends on acid or base added to neutralize.) What is a weak acid? - Answer-an acid that only partially ionizes in an aqueous solution. This...

What does it mean that the heat of a reaction is an extensive property? 2. (3 points) Does the following reaction give off heat or absorb heat? Explain briefly. C D H = +263Kcal/mol 3. (4 points) In one experiment in the video, room temperature water was mixed with water at about 38 degrees. To what temperature (about) did the mixture of the two water samples come to after setting for a few minutes? Answer: 1. The heat depends on the amount of substance. If the amount of substance is d...

Metabolism (catabolism and anabolism) - Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anabolism: the process by which simple products and building blocks of catabolism are us...

accuracy - how close a measurement is to a true or accepted value acid - proton donor Acid Naming Rules - 1. Add O, add "per" prefix. 2. Subtract 1 O, ending in "ous". 3. Subtract 2 O's, add "hypo" prefix with "ous" suffix. acid-base titration - a solution of a known concentration (standard) is added gradually to another in order to determine the concentration actual yield - the amount of actual product formed in a reaction Ag⁺ - Silver cation Al³⁺ - Aluminum cation allot...
