He coined the term chemistry" (in french) and published the first article in a scientific journal about a chemical experiment. c. Lavoisier was the first to measure the energy changes in a chemical reaction, measurements that led ultimately to the law of conservation of energy. d. He was the first to apply quantitative measurements to a chemical problem. He welghed out the reactants and the products of a chemical reaction before and after the reaction. What he leamed became the law of conservation of matter The tin (l) or stannous ion is Sn2 What is true about the stannic ion? Select one o a. It will have a greater charge than the stannous ion. b. It will have a lesser charge than the stannous ion. c It will contain a hydrogen atom d It will contain a oxygen atom e.
