Question

When silver tarnish reacts with aluminum metal in a basic solution, resulting in the formation of silver metal, hydrogen sulfide, and aluminum oxide. What type of reaction is being described?

A) Synthesis
B) Decomposition
C) Single Replacement
D) Double Replacement

Answer 1

The described reaction is a single replacement reaction, where aluminum displaces silver, resulting in the formation of silver metal, hydrogen sulfide, and aluminum oxide.

Step-by-step explanation:

The reaction between silver tarnish and aluminum metal in a basic solution results in silver metal, hydrogen sulfide, and aluminum oxide. This is a type of single replacement reaction, where aluminum displaces silver from its compound. The aluminum gets oxidized, while the silver ions are reduced to silver metal. Single-displacement reactions are characterized by one element being replaced by another in a compound.
