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。
Types of Particles in Nuclear Reactions How to Balance Nuclear Equations Examples of Balancing Nuclear Equations Lesson Summary Frequently Asked Questions Why must nuclear equations be balanced? Nuclear equations need to be balanced to follow the law of conservation of mass. Mass is neither cre...
Balancing chemical equations is possible because of the law of conservation of matter. Understand how to balance chemical equations step by step...
A method of balancing equations that involves only two variables will be presented. The method is applicable to all types of equations, including redox equations and net ionic equations. No reference to half-reactions, oxidation numbers, or number of electrons gained/lost is necessary. Some equatio...
