CHAPTER 9 CHEMICAL REACTIONS AND EQUATIONSH O→ HO
1. 每一种元素必须在等式的每一侧具有相同数量的原子(质量守恒定律)。 2. 只可以通过调整系数来对方程进行配平。 NaNa不是一个已配平的元素。要配平NaNa,将左边的NaHCO3NaHCO3乘以22。 2NaHCO3→Na2CO3+H2O+CO22NaHCO3→Na2CO3+H2O+CO2 HH是一个已配平的元素,因为HH在等式两边有相同的原子数目。 HH是...

In reactions under normal laboratory conditions, matter is neither created nor destroyed, and elements are not transformed into other elements. Therefore, equations depicting reactions must be balanced; that is, the same number ofatomsof each kind must appear on opposite sides of the equation. The...
A balanced chemical equation is when: Both the numbers of each type of atom and the total charge are the same on both sides A chemical reaction represents a change in the distribution of atoms but not in the number of atoms Balancing Equations & Chemical Reactions Occur when bonds are formed...
