Read each question carefully and provide your best answer. This worksheet covers different types of chemical reactions.
1. Which type of reaction combines two or more reactants to form a single, more complex product?
Decomposition reaction
Synthesis reaction
Single displacement reaction
Double displacement reaction
2. The reaction 2H₂O → 2H₂ + O₂ is an example of a:
Synthesis reaction
Decomposition reaction
Combustion reaction
Single displacement reaction
1. In a single displacement reaction, a more reactive element displaces a less reactive element from its compound.
True
False
2. Combustion reactions always produce oxygen gas as a product.
True
False
1. A reaction where two ionic compounds exchange ions to form two new compounds is called a reaction.
2. The rapid reaction between a substance with oxygen, producing heat and light, is known as a reaction.
1. Describe the key difference between a single displacement reaction and a double displacement reaction.
Match each reaction type with its general form.
1. Synthesis
a. AB → A + B
2. Decomposition
b. A + BX → AX + B
3. Single Displacement
c. AX + BY → AY + BX
4. Double Displacement
d. A + B → AB
