Describing Chemical Reactions
Chemical reactions are processes that involve the rearrangement of atoms and molecules to form new substances. They are fundamental to life and play a vital role in various natural and industrial processes.
Types of Chemical Reactions, Describing chemical reactions worksheet answers
- Combination reactions: Two or more substances combine to form a single product.
- Decomposition reactions: A single substance breaks down into two or more products.
- Single-displacement reactions: One element replaces another element in a compound.
- Double-displacement reactions: Two compounds exchange ions to form two new compounds.
Role of Reactants and Products
Reactantsare the starting materials of a chemical reaction, while productsare the substances formed as a result of the reaction. The reactants are consumed during the reaction, and the products are produced.
Worksheet Answers
Worksheet Question 1:Identify the type of reaction for the following equation: 2Na + Cl 2→ 2NaCl
Answer:Combination reaction
Reasoning:Two elements, sodium (Na) and chlorine (Cl), combine to form a single product, sodium chloride (NaCl).
Worksheet Question 2:Write the balanced equation for the decomposition of water into hydrogen and oxygen.
Answer:2H 2O → 2H 2+ O 2
Reasoning:Water (H 2O) breaks down into two products, hydrogen (H 2) and oxygen (O 2).
Worksheet Question 3:What is the type of reaction when zinc displaces copper from copper sulfate solution?
Answer:Single-displacement reaction
Reasoning:Zinc (Zn) replaces copper (Cu) in copper sulfate (CuSO 4) to form zinc sulfate (ZnSO 4) and copper (Cu).
