Chem1211 Stoichiometry of Chemical Reactions (Writing and Balancing Chemical Equations). 1. What does it mean to say an equation is balanced? Why is it important for an equation to be balanced? Solution An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter. 2. Consider molecular, complete ionic, and net ionic equations. (a) What is the difference betw...

HESI A2 CHEMISTRY STUDY GUIDE QUESTIONS AND ANSWER KEY Atom The atom is the smallest unit of matter. Every atom contains one nucleus at least one electron. The nucleus contains at least one positively charged proton and an equal number of neutrally charged neutrons. Every atom also has at least one negatively charged electron bound to the nucleus. When the number of protons (the atomic number) is equal to the number of electrons, the atom is neutral. When the number of protons and number of ...
