Question

Ca - CaO — Ca(OH), — CaZnO2 → ZnSO,

Answer 1

Ответ:

Объяснение:

2Ca + O₂ = 2CaO

CaO + H₂O = Ca(OH)₂

Ca(OH)₂ + Zn(OH)₂ = CaZnO₂ + 2H₂O

CaZnO₂ + Na₂SO₄ = CaSO₄↓ + Na₂ZnO₂

Answer 2

It seems like you've provided a sequence of chemical reactions involving different compounds. However, there seems to be a slight error in the representation of the compounds and reactions you've written. Let me correct and explain the reactions for you:

1. Ca (Calcium) reacts with O2 (oxygen) to form CaO (calcium oxide), commonly known as quicklime:

   Copy code
   2 Ca + O2 → 2 CaO
   

2. CaO (calcium oxide) reacts with water (H2O) to produce Ca(OH)2 (calcium hydroxide), also known as slaked lime:

   scssCopy code
   CaO + H2O → Ca(OH)2
   

3. The third reaction you've written is not correctly represented. Assuming you're referring to a reaction where calcium hydroxide reacts with zinc oxide, it would be something like:

   scssCopy code
   Ca(OH)2 + ZnO → CaZnO2 + H2O
   

   This reaction produces CaZnO2 (calcium zincate) and water (H2O).

4. The final reaction is not clear based on your provided information. However, you've mentioned "ZnSO," which could be zinc sulfate. If you meant that, the reaction could be:

   Copy code
   ZnO + H2SO4 → ZnSO4 + H2O
   

   This reaction involves ZnO (zinc oxide) reacting with H2SO4 (sulfuric acid) to produce ZnSO4 (zinc sulfate) and water (H2O).

Please verify if these corrected reactions match your intended sequence of chemical transformations. If you have any further questions or need additional information, feel free to ask!
