Расставьте коэффициенты в уравнениях и определите тип химических реакций:
NaHCO3 -> Na2CO3 + CO2 + H2O
Fe + AgNO3 -> Fe(NO3)2 + Ag
P + O2 -> P2O5
KOH + H3PO4 -> K3PO4 + H2O
H2SO3 + Al -> Al2(SO3)3 + H2
Ca(OH)2 + HNO3 -> Ca(NO3) + H2O
Al + CaCl2 -> AlCl3 +Ca
KNO3 -> KNO2 + O2
CaCl2 +AgNO3 -> AgCl + Ca(NO3)2
