c = 3 (H2O) d = 6 (C2H5NH3Cl) f = 1 (Al2O3) 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.6 ...
写出丙酰氯与下列试剂反应的主要产物(1)H2O,Δ (2)C2H5OH,Δ (3)C6H5OH,Δ (4)CH3NH2,Δ (5)C6H5NH2,Δ
替换不可改变的组以避免歧义。例如,C6H5C2H5 + O2 = C6H5OH + CO2 + H2O不能被平衡,但XC2H5 + O2 = XOH + CO2 + H2O可以。 不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。 例子 CH3COCH3 + Br2 + KOH = CH3COCH2Br + KBr + H2O ...

every element in C2H5NH2 + HCl = C2H5NH3 + Cl2 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 ...
