We just leave out the so-called spectator ions: nitrate and sodium, which don't participate directly in the reaction, and end up with a net ionic equation showing just silver and chloride ions reacting to form silver chloride.

我们只是忽略了所谓的旁观离子:硝酸盐和钠, 它们不直接参与反应,最终得到一个净离子方程式, 显示只有银离子和氯离子反应形成氯化银。

化学方程序 Chemical equation

(重定向自Ionic equation)

化学方程序化学反应方程序(Chemical equation)是用来描述各种物质之间的不同化学反应的式子。

化学方程序反映的是客观事实。因此书写化学方程序要遵守两个原则:一是必须以客观事实为基础,绝不能凭空臆想、臆造事实上不存在的物质和化学反应;二是要遵守质量守恒定律,等号两边各原子种类与数目必须相等。

Chemical equation 化学方程式

(重定向自Ionic equation)
As seen from the equation CH4 + 2 O2 → CO2 + 2 H2O, a coefficient of 2 must be placed before the oxygen gas on the reactants side and before the water on the products side in order for, as per the law of conservation of mass, the quantity of each element does not change during the reaction
P4O10 + 6 H2O → 4 H3PO4This chemical equation is being balanced by first multiplying H3PO4 by four to match the number of P atoms, and then multiplying H2O by six to match the numbers of H and O atoms.

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers. The first chemical equation was diagrammed by Jean Beguin in 1615.
