Answer 2

Here are the chemical reactions for the given compounds and their reactions with other substances:

1. Al(OH)3 (Aluminum hydroxide): Al(OH)3 does not readily react with atmospheric moisture or common acids. However, it can react with strong acids, such as hydrochloric acid (HCl), to form aluminum chloride and water.

   Reaction: Al(OH)3 + 3HCl → AlCl3 + 3H2O

2. ZnO (Zinc oxide): Zinc oxide can react with hydrochloric acid (HCl) to form zinc chloride and water.

   Reaction: ZnO + 2HCl → ZnCl2 + H2O

3. CaO (Calcium oxide): Calcium oxide, also known as quicklime, is highly reactive with water, producing calcium hydroxide (slaked lime) through an exothermic reaction.

   Reaction: CaO + H2O → Ca(OH)2

4. HNO3 (Nitric acid) + Ba(OH)2 (Barium hydroxide): Nitric acid can react with barium hydroxide to form barium nitrate and water.

   Reaction: 2HNO3 + Ba(OH)2 → Ba(NO3)2 + 2H2O

5. H3PO4 (Phosphoric acid) + Na (Sodium): Phosphoric acid can react with sodium to form sodium phosphate and hydrogen gas.

   Reaction: 2H3PO4 + 6Na → 2Na3PO4 + 3H2

Please note that these are simplified representations of the reactions. Reaction conditions and stoichiometry may vary depending on the specific concentrations, temperatures, and other factors involved.

Answer 3

Here are the chemical reactions you've listed:

1. Al(OH)₃ (aluminum hydroxide) has a neutralization reaction with HCl (hydrochloric acid):

   Al(OH)₃ + 3 HCl → AlCl₃ + 3 H₂O

2. ZnO (zinc oxide) reacts with HCl (hydrochloric acid) to form zinc chloride and water:

   ZnO + 2 HCl → ZnCl₂ + H₂O

3. CaO (calcium oxide) reacts with H₂O (water) in a process known as slaking to form calcium hydroxide (Ca(OH)₂):

   CaO + H₂O → Ca(OH)₂

4. HNO₃ (nitric acid) reacts with Ba(OH)₂ (barium hydroxide) in a double displacement reaction:

   2 HNO₃ + Ba(OH)₂ → 2 Ba(NO₃)₂ + 2 H₂O

5. H₃PO₄ (phosphoric acid) can react with sodium (Na) in various ways depending on the conditions. One possible reaction is the formation of sodium dihydrogen phosphate:

   H₃PO₄ + NaOH → NaH₂PO₄ + H₂O

Please note that these are simplified representations of the reactions, and in reality, there can be various factors, concentrations, and conditions that might influence the exact outcomes of these reactions.
