Chemical Reactions

The given chemical equations represent various chemical reactions. Let's break down each reaction and identify the products formed.

1. CaO + H2O → Ca(OH)2 - When calcium oxide (CaO) reacts with water (H2O), it forms calcium hydroxide (Ca(OH)2) .

2. NH4NO2 → N2 + H2O - Ammonium nitrite (NH4NO2) decomposes into nitrogen gas (N2) and water (H2O) .

3. CuO + H2 → Cu + H2O - Copper(II) oxide (CuO) reacts with hydrogen gas (H2) to produce copper (Cu) and water (H2O) .

4. Fe(OH)3 → Fe2O3 + H2O - Iron(III) hydroxide (Fe(OH)3) decomposes to form iron(III) oxide (Fe2O3) and water (H2O) .

5. 2Al + 3Cl2 → 2AlCl3 - When aluminum (Al) reacts with chlorine gas (Cl2), it forms aluminum chloride (AlCl3) .

These reactions involve different types of chemical transformations, including decomposition, combination, and displacement reactions. If you have any specific questions about these reactions or related topics, feel free to ask!
