Make an equation: SO3 → H2SO4 → ZnSO4 → Zn (OH) 2 → ZnO
| May 23, 2021 | education
H2O + SO3 = H2SO4 (sulfuric anhydride, reacting with water, forms concentrated sulfuric acid)
Zn + H2SO4 = ZnSO4 + H2 ↑ (zinc sulfate is obtained by reacting zinc with sulfuric acid)
ZnSO4 + 2NaOH = Zn (OH) 2 + Na2SO4 (zinc sulfate, reacting with alkalis, forms zinc hydroxide)
Zn (OH) 2 = ZnO + H2O (thermal decomposition of hydroxide into oxide and water)
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
