Question

Осуществите цепочку превращений: Ba - BaO - Ba(OH)2 - BaCl2

Answer 1

2BA+O2====2BAO

BAO+H2O==BA(OH)2

BA(OH)2+2HCL==BACL2+2H2O

Answer 2

Transformation Chain: Ba -> BaO -> Ba(OH)2 -> BaCl2

To transform Ba into BaCl2, the following steps can be taken:

1. Ba -> BaO - Ba + O2 = BaO 2. BaO -> Ba(OH)2 - BaO + H2O = Ba(OH)2 [[3]](https://otvet.mail.ru/question/24797423)

3. Ba(OH)2 -> BaCl2 - Ba(OH)2 + 2HCl = BaCl2 + 2H2O [[3]](https://otvet.mail.ru/question/24797423)

Therefore, the transformation chain for Ba -> BaO -> Ba(OH)2 -> BaCl2 involves the above chemical reactions.
