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...

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...
