Counting oxygen atoms - Guides d'étude, Notes de cours & Résumés

Quiz: Charlie is balancing an equation. She has identified the atoms and counted the number of each in the reactants and products. What would Charlie adjust to make the number of atoms in the reactants the same as the number of atoms in the products? Ans: coefficients Quiz: If the number of atoms in the reactants equals the number of atoms in the products, the equation is Ans: balanced Quiz: Kiley wants to balance the equation H2 + N2 → NH3. Which would be her first step in balan...
