Question

Zn + O2 →2ZnO Cu + O2 +CuО2 Fe + O2 +2Fe2O3 Ca + O2 +2CaО Sr+ O2 +2SrО Ba + 2О→

Answer 1

Ответ:

2Zn + O₂ →2ZnO

2Cu + O₂ = 2CuО

4Fe + 3O₂  =2Fe₂O₃

2Ca + O₂  =2CaО

2Sr+ O₂  =2SrО

2Ba + О₂→ 2BaO

Объяснение:

Answer 2

It looks like you've provided a series of chemical reactions involving different elements and oxygen. These reactions represent the formation of various metal oxides.

1. Zn + O2 → 2ZnO (Zinc reacts with oxygen to form zinc oxide)
2. Cu + O2 → 2CuO (Copper reacts with oxygen to form copper(II) oxide)
3. Fe + O2 → 2Fe2O3 (Iron reacts with oxygen to form iron(III) oxide, commonly known as rust)
4. Ca + O2 → 2CaO (Calcium reacts with oxygen to form calcium oxide)
5. Sr + O2 → 2SrO (Strontium reacts with oxygen to form strontium oxide)
6. Ba + O2 → 2BaO (Barium reacts with oxygen to form barium oxide)
