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 или
f) 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.
получится взрыв, надо добавить чуть чуть кислорода объяснение:
Cxhy + 02 = x co2 + y/2 h2o
объяснение:
2hcl + mg mgcl + h2 n(hcl): n(mg = 2: 1 m(hcl) = 36,5 * 2 MONB = = = = m(mg) = 73 24 m(hcl): n(mg) = 3: 1 agno3 + hcl = agcl + hno3 n(agno3): = n(hcl) = 1: 1 m(agno3) = 170 m(hcl) = 36,5 m(agno3) : n(hcl) = 5: 1 = cu(no3)2 + 2naoh = cu(oh)2 + 2nano3 n(cu(no3)2) : n (nsoh) = 1: 2 = = m(cu(no3)2) = 187,5 m(naoh) = 2* 40 = 80 m(cu(no3)2): m(naoh) = 2: = = = 1
ответ: m(p-ра) - 40°100/25-160 = m(h2o) = 160-40120
