Types of Reactions and Their Definitions

There are several types of reactions mentioned in your question. Let's go through each one and define their types.

1. K + H₂ = KH + KOH: This is a combination reaction, also known as a synthesis reaction. It occurs when two or more substances combine to form a single product. In this case, potassium (K) and hydrogen gas (H₂) combine to form potassium hydride (KH) and potassium hydroxide (KOH).

2. H₂SO4 = K₂SO4 + 2H₂O: This is a decomposition reaction. It occurs when a single compound breaks down into two or more simpler substances. In this case, sulfuric acid (H₂SO4) decomposes into potassium sulfate (K₂SO4) and water (H₂O).

3. CaCO3 = CaO + CO₂: This is also a decomposition reaction. Calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO₂).

4. NaOH + P₂O5 = Na3PO4: This is a combination reaction. Sodium hydroxide (NaOH) and diphosphorus pentoxide (P₂O5) combine to form sodium phosphate (Na3PO4).

5. H₂O + SO₂ = SO₃: This is a combination reaction. Water (H₂O) and sulfur dioxide (SO₂) combine to form sulfur trioxide (SO₃).

6. O₂ + H₂CO3 = CO₂ + H₂O: This is a decomposition reaction. Oxygen gas (O₂) reacts with carbonic acid (H₂CO3) to produce carbon dioxide (CO₂) and water (H₂O).

7. Fe₂O₃ + H₂ = Fe + H₂O: This is a redox reaction, specifically a reduction reaction. Iron(III) oxide (Fe₂O₃) reacts with hydrogen gas (H₂) to produce iron (Fe) and water (H₂O).

8. FeCl₃ + NaOH = Fe(OH)₃ + NaCl: This is a double displacement reaction, also known as a metathesis reaction. Iron(III) chloride (FeCl₃) reacts with sodium hydroxide (NaOH) to produce iron(III) hydroxide (Fe(OH)₃) and sodium chloride (NaCl).

9. CO + O₂ = CO₂: This is a combination reaction. Carbon monoxide (CO) reacts with oxygen gas (O₂) to produce carbon dioxide (CO₂).

These are the types of reactions and their definitions based on the given chemical equations.
