Oxidize - correct answer When a substance LOSES its electrons. Reduced - correct answer When a substance GAINS its electrons. Redox Reaction - correct answer The net reaction of oxidation and reduction. Oxidation and Reduction - correct answer Occur together in ONE reaction. Oxidizing Agent - correct answer A substance that gets reduced causes another substance to be oxidized. Reducing Agent - correct answer A substance that gets oxidized cause anothe...

Double-displacement reaction - answer-is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. Precipitate - answer-is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension. (precipitates can form when two soluble salts react in solution to form one or more insoluble products) Energy levels - answer-(also ...

©THEBRIGHTSTARS 2024 Chapter 1 Unit 4 Electricity Questions With Correct Answers The movement of electrons to perform a useful function is called static electricity - answerFalse For current to flow from the power source through the load and then back to the source, the current path must be conductive - answerTrue To force electrons to move, some form of energy must be applied to the electrons to cause them to leave their atom, this energy can only be supplied by magnetism. - answerFals...
