Напишите ровняние реакций zn(oh)2-> k2zno2-> zn3(po4)2-> znhpo4-> h3po4-> hpo3

1) a) zn(oh)2 + 2koh (+t) = k2zno2 + 2h2o,b) 3k2zno2 + 4h3po4 = 2k3po4 + zn3(po4)2 + 6h2o,c) zn3(po4)2 + h3po4 = 3znhpo4,d) 2znhpo4 (+t) = zn2p2o7 + h2o или так 3znhpo4 (+t) = zn3(po4)2 + h3po4,e) zn2p2o7 + 2h2so4 = 2znso4 + h4p2o7 и далее h4p2o7 (+t) = 2hpo3 + h2o илиf) 2h3po4 (+t) = h4p2o7 + h2o и далее h4p2o7 (+t) = 2hpo3 + h2o;     2) a) ch4 + cl2 (+hv) = ch3cl + hcl,b) ch3cl + 2nh3 (+t) = ch3nh2 + nh4cl,c) ch3nh2 + nano2 + hcl = ch3oh + nacl + n2 + h2o,d) ch3oh + hcooh (+t, +h+) = hcooch3 + h2o,e) hcooch3 + koh (+t) = ch3oh + hcook.

[(0,5х+0,1у)/(х+у)]*100=30

5х+у=3х+3у

5х-3х=3у-у

2х=2у
