K+1OH-1
Mg+2S+6O-2
Al+3(O-2H+1)3
NiO + 2H (+) = Ni (2+) + H2O
1) C3H7Cl + KOH --- C3H7OH + KCl
2) C5H10Cl2 + 2Mg --- C5H10 + 2MgCl
2Me + 2H2O = 2MeOH + H2
n(H2) = V/Vm = 4.48/22.4 = 0.2 моль
По уравнению реакции:
n(Me) = 0.2*2/1 = 0.4 моль
M(Me) = m/n = 9.2/0.4 = 23 г/моль
Me - Na натрий
а) C + O2 = CO2
CO2 + H2O = H2CO3
2KOH + H2CO3 = K2CO3 + 2H2O
б) 2Ba + O2 = 2BaO
BaO + H2O = Ba(OH)2
Ba(OH)2 + 2HCl = BaCl2 + 2H2O
