Place the coefficients in the reaction equations, if necessary, indicate the type of reaction: 1) NaOH + H2SO4 → Na2SO4 + H2O; 2) Fe2O3 + Al → Al2O3 + Fe; 3) P + O2 → P2O5; 4) CaCO3 + HCl → CaCl2 + H2CO3; 5) H2O2 → H2O + O2; 6) Fe2O3 + C → Fe + CO2;
2NaOH + H2SO4 → Na2SO4 + 2H2O. Exchange reaction.
Fe2O3 + 2Al → Al2O3 + 2Fe. Substitution reaction, redox (ORR).
4P + 5O2 → 2P2O5. Compound reaction, OVR.
CaCO3 + 2HCl → CaCl2 + H2CO3. Exchange reaction.
2H2O2 → 2H2O + O2. Decomposition reaction, ОВР.
2Fe2O3 + 3C → 4Fe + 3CO2. Substitution reaction, OVR.
