СО2 + н2о=Н2СО3( т.к и в делай и в правой части водородов и кислородов равное количество )
Р2О5 +3Н2О=2Н3РО4( мы умножаем в правой части на 2( т.к в левой у нас 2 фосфора ) после это подсчитываем водороды , видим что они не равны (т.к в левой их 2 , а в правой уже 6) соответственно мы умножаем воду на 3, чтобы сравнять количества водородов . Дальше все так же, только разные коэффициенты будут
