BaCl2 + Na2SO4 = BaSO4↓ + 2NaClBa + Cl + Na + SO4 = Ba + SO4 + NaClBa + SO4 = BaSO4↓
Fe(NO3)3 + NaOH = Fe(OH)3↓ + 3NaNO3Fe + NO3 + Na + OH = Fe + OH + NaNO3Fe + OH = Fe(OH)3↓
BaCl2 + Na2SO4 = BaSO4↓ + 2NaCl
Ba + Cl + Na + SO4 = Ba + SO4 + NaCl
Ba + SO4 = BaSO4↓
Fe(NO3)3 + NaOH = Fe(OH)3↓ + 3NaNO3
Fe + NO3 + Na + OH = Fe + OH + NaNO3
Fe + OH = Fe(OH)3↓
