Answer 1

Synthesis Reactions: Formation of water from hydrogen and oxygen, Formation of sodium chloride from sodium and chlorine, Formation of potassium chloride from potassium and chlorine, Formation of iron oxide from iron and oxygen. Decomposition Reaction: Decomposition of water into hydrogen and oxygen, Decomposition of calcium carbonate into calcium oxide and carbon dioxide.

Here are the chemical equations categorized as synthesis and decomposition reactions:

Synthesis Reactions:

1.
`\( 2 \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O} \)` (Formation of water from hydrogen and oxygen)

2.
`\( 4 \text{Na} + \text{Cl}_2 \rightarrow 4 \text{NaCl} \)` (Formation of sodium chloride from sodium and chlorine)

3.
`\( \text{K} + \text{Cl}_2 \rightarrow \text{KCl} \)` (Formation of potassium chloride from potassium and chlorine)

4.
`\( \text{Fe} + \text{O}_2 \rightarrow \text{Fe}_2\text{O}_3 \)` (Formation of iron oxide from iron and oxygen)

Decomposition Reaction:

1.
`\( 2 \text{H}_2\text{O} \rightarrow 2 \text{H}_2 + \text{O}_2 \)` (Decomposition of water into hydrogen and oxygen)

2.
`\( \text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2 \)` (Decomposition of calcium carbonate into calcium oxide and carbon dioxide)

Answer 2

Synthesis reactions:

• Iron + oxygen → iron oxide
• sodium + chlorine → sodium chloride
• sulfur + oxygen → sulfur dioxide

Decomposition reactions:

• Water → hydrogen + oxygen
• Calcium carbonate → carbon oxide + carbon dioxide

Step-by-step explanation:

• Synthesis reactions are reactions in which products combine to form a compound as the product. For example, iron and oxygen combine to form compound iron oxide.
• Decomposition reactions involve the breakdown of a compound into constituent elements or smaller compounds.
• For example, calcium carbonate is broken down into smaller compounds calcium oxide and calcium dioxide.
• Water is broken down into individual elements of oxygen and hydrogen.
