NaOH = CuH2O2 + Na2S must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced....

A、将V1mL c1mol/L的NaOH溶液滴加到V2mL c2mol/L的CH3COOH 溶液混合,若V1=V2,c1=c2,二者恰好完全反应生成CH3COONa,CH3COONa为强碱弱酸盐,溶液呈碱性,则c(H+)<c(OH-),故A错误;B、醋酸为弱酸,若c1V1=c2V2时,二者恰好完全反应生成CH3COONa,溶液呈碱性,若混合溶液的pH=7,则一定存在c1V1<c2V2,故B正确;...
b = 1 (NaOH) c = 1 (H(OH)) d = 1 (Na(NO3)) Step 4: Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. ...
