Question

Question: How are chemical reactions classified? Match: Most chemical reactions can be classified as one of five types. Match the following definitions to the type of reaction. Synthesis Decomposition Single replacement Double replacement Combustion One reactant is broken down into two or more products. A fuel is combined with oxygen to produce carbon dioxide and water Two or more reactants combine to form one product. Two compounds react to form two different compounds. A compound reacts with an element to form a new compound and a different element. One reactant is broken down into two or more products. A fuel is combined with oxygen to produce carbon dioxide and water Two or more reactants combine to form one product. Two compounds react to form two different compounds. A compound reacts with an element to form a new compound and a different element.

Answer 1

Here are the definitions matched to the corresponding types of chemical reactions:

1. Synthesis: Two or more reactants combine to form one product.

2. Decomposition: One reactant is broken down into two or more products.

3. Single replacement: A compound reacts with an element to form a new compound and a different element.

4. Double replacement: Two compounds react to form two different compounds.

5. Combustion: A fuel is combined with oxygen to produce carbon dioxide and water.

So the complete matches are:

• Synthesis: Two or more reactants combine to form one product.
• Decomposition: One reactant is broken down into two or more products.
• Single replacement: A compound reacts with an element to form a new compound and a different element.
• Double replacement: Two compounds react to form two different compounds.
• Combustion: A fuel is combined with oxygen to produce carbon dioxide and water.
