Уравнение реакции, например:
2FeO + C ----> 2Fe + CO2
Из 1 моля (56+16) = 72 г оксида железа можно получить 1 моль (56г)железа, значит из 144 грамм (2 моля) получится 112 г (2 моля) железа
1) c2h6 = c2h4 + h2
2) c2h4 + h2o =(hg2+) c2h5oh (реакция кучерова)
3) c2h5oh + cuo =(t) ch3cho + cu + h2o
4) ch3cho + ag2o = ch3cooh + 2ag
5) ch3cooh + cl2 = clch2cooh + hcl
6) clch2cooh + 2nh3 = nh2ch2cooh + nh4cl
7) n nh2ch2cooh = (-nhch2co-)n + n h2o
M воды =300г
m в-ва=30.6г
m р-ра=вода +в-во=300г+30,6=306.6г
омега w=mв-ва/mр-ра *100\%=30,6/306.6*100\%=9,9~10\%
