Question

BaO—> Ba(OH)2–> BaS—> Ba(NO3)2

Answer 1

BaO + H2O = Ba(OH)2

Ba(OH)2 + H2S = BaS + 2H2O

BaS + 2AgNO3 = Ba(NO3)2 + Ag2S

Answer 2

The sequence of chemical reactions you provided involves the transformation of barium oxide (BaO) into barium nitrate (Ba(NO3)2) via intermediate compounds. Let's go through each step:

1. BaO -> Ba(OH)2: Barium oxide (BaO) reacts with water (H2O) to form barium hydroxide (Ba(OH)2) according to the following equation: BaO + H2O -> Ba(OH)2

2. Ba(OH)2 -> BaS: Barium hydroxide (Ba(OH)2) reacts with hydrogen sulfide (H2S) to produce barium sulfide (BaS) and water (H2O). The reaction can be represented as follows: Ba(OH)2 + H2S -> BaS + 2H2O

3. BaS -> Ba(NO3)2: Barium sulfide (BaS) reacts with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2) and hydrogen sulfide (H2S): BaS + 2HNO3 -> Ba(NO3)2 + H2S

Therefore, the overall sequence of reactions is: BaO + H2O -> Ba(OH)2 Ba(OH)2 + H2S -> BaS + 2H2O BaS + 2HNO3 -> Ba(NO3)2 + H2S

Note that these reactions involve specific conditions such as temperature, pressure, and concentrations to proceed effectively.
