Question

Химия: 2hcl+naso3=2nacl+so2+h2o m(hcl)=14г. найти v(so2)

stigma70 · Answer

1. Na2SO3 + HCl → SO2 + NaCl + H2O

2. Zn + Na2SO3 + HCl → ZnCl2 + H2S + NaCl + H2O

3. Na2SO3 + KMnO4 + HCl → MnCl2 + Na2SO4 + KCl + H2O

4. Na2SO3 + K2Cr2O7 + HCl → CrCl3 + Na2SO4 + KCl + H2O

5. Na2SO3 + HCl → H2SO3 + NaCl

6. H2S + Na2SO3 + HCl → S + NaCl + H2O

7. Na2S + Na2SO3 + HCl → S + NaCl + H2O

8. Mg + Na2SO3 + HCl → MgCl2 + H2S + NaCl + H2O

9. Na2SO3 + SnCl2 + HCl → SnS2 + SnCl4 + NaCl + H2O

10. Na2SO3 + K2Cr2O7 + HCl → CrCl2 + Na2SO4 + KCl + H2O
