This is an incomplete question, the complete question is given below.
Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Match the reactants with the products.
copper sulfate + oxygen
copper oxide
zinc sulfate + copper
aluminum chloride + copper
copper + water
copper sulfate + zinc →
aluminum + copper chloride →
copper oxide + hydrogen →
copper + oxygen →
Answer :
Copper sulfate + Zinc → Zinc sulfate + copper
Aluminium + Copper chloride → Aluminium chloride + copper
Copper oxide + Hydrogen → Copper + Water
Copper + Oxygen → Copper oxide
Explanation :
As we know that chemical reaction is a reaction in which two or more than two substances or reactants are reacted to give two or more than two different products.
According to the question:
- Copper sulfate + Zinc → Zinc sulfate + copper
This reaction is a single replacement reaction in which zinc is more reactive than copper and zinc displaces copper from its salt to give products.
- Aluminium + Copper chloride → Aluminium chloride + Copper
This reaction is a single replacement reaction in which aluminium is a more reactive element than copper and aluminium displaces copper from its salt to give products.
- Copper oxide + Hydrogen → Copper + water
This reaction is a single replacement reaction in which hydrogen displaces less reactive metals from their oxide to form water and the metal.
- Copper + Oxygen → Copper oxide
This reaction is a synthesis reaction in which two different atoms or molecules combine to form single compound.
Answer:
Copper sulfate + Zinc → Zinc sulfate + copper
Aluminium + Copper chloride → Aluminium chloride + copper
Copper oxide + Hydrogen → Copper + Water
Copper + Oxygen → Copper oxide
