Gen Chem 1 Final Exam Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is the principle behind the law of conservation of mass in a chemical reaction? The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products. How do you determine the number of valence electrons in an atom? The number of valence electrons can be determined by the group number of the eleme...
