Question

1) Cl2 → NaClO → HClO → Ca(OCl)2 → Cl2 2) N2 → NH3 → N2 → NO → NO2 → HNO3 → NO

Answer 1

1)
2NaOH + Cl2 = NaCl + NaClO + H2O
NaClO + H2O = HClO + NaOH
2HClO + Ca(OH)2 = Ca(ClO)2 + 2H2O
Ca(ClO)2 + 4HCl = CaCl2 + 2Cl2↑ + 2H2O
2)
3H2 + N2 = 2NH3
6NO + 4NH3 = 5N2 + 6H2O
N2 + O2 = 2NO
2NO + O2 = 2NO2
2NO2 + H2O = HNO2 + HNO3
3Cu + 8HNO3 = 3Cu(NO3)2 + 4H2O + 2NO↑

Answer 2

It appears that you've provided two sequences of chemical reactions. Let me provide some explanations for each of these sequences:

1. Cl2 → NaClO → HClO → Ca(OCl)2 → Cl2 This sequence of reactions seems to involve the transformation of chlorine gas (Cl2) into calcium hypochlorite (Ca(OCl)2) and back into chlorine gas. Here's how this sequence could be explained:

   a. Cl2 is reacting with sodium hydroxide (NaOH) or a similar base to form sodium hypochlorite (NaClO). This reaction can be represented as: Cl2 + 2NaOH → 2NaClO + H2O

   b. Sodium hypochlorite (NaClO) can decompose to form hypochlorous acid (HClO): NaClO → HClO + NaOH

   c. Hypochlorous acid (HClO) might react with calcium ions (Ca2+) to form calcium hypochlorite (Ca(OCl)2): 2HClO + Ca(OH)2 → Ca(OCl)2 + 2H2O

   d. Finally, calcium hypochlorite (Ca(OCl)2) can release chlorine gas (Cl2) in a suitable reaction.

2. N2 → NH3 → N2 → NO → NO2 → HNO3 → NO This sequence of reactions involves the conversion of nitrogen gas (N2) into various nitrogen-containing compounds. Here's how this sequence could be explained:

   a. N2 reacts with hydrogen (H2) to form ammonia (NH3). This is known as the Haber-Bosch process: N2 + 3H2 → 2NH3

   b. Ammonia (NH3) can be converted back into nitrogen gas (N2) through various reactions.

   c. Nitrogen gas (N2) can react with oxygen (O2) to form nitrogen monoxide (NO): N2 + O2 → 2NO

   d. Nitrogen monoxide (NO) can further react with oxygen to form nitrogen dioxide (NO2): 2NO + O2 → 2NO2

   e. Nitrogen dioxide (NO2) can dissolve in water to form nitric acid (HNO3): 3NO2 + H2O → 2HNO3 + NO

   f. Nitric acid (HNO3) can release nitrogen monoxide (NO) through various reactions.

Please note that these sequences are a simplification, and the actual chemical reactions may involve more steps or intermediates. The reversibility of some reactions might not be straightforward in practice, and the conditions under which these reactions occur would need to be considered.
