Question

Cân bằng phương trình phản ứng:

Mg+O₂---->MgO

Zn+O₂---->ZnO

Cu+O₂---->CuO

Answer 1

\(2Mg+O_2\underrightarrow{t^o}2MgO\)

\(2Zn+O_2\underrightarrow{t^o}2ZnO\)

\(2Cu+O_2\underrightarrow{t^o}2CuO\)

Answer 2

\(2Mg+O_2\rightarrow2MgO\)

\(2Zn+O_2\rightarrow2ZnO\)

\(2Cu+O_2\rightarrow2CuO\)

Answer 3

2Mg + O₂ → 2MgO

2Zn + O₂ → 2ZnO

2Cu + O₂ → 2CuO

Answer 4

2Mg+O₂--t^o-->2MgO

2Zn+O₂--t^o-->2ZnO

2Cu+O₂--t^o-->2CuO
