Turning Zinc into Silver: Single Replacement Reaction Demo

The video tutorial explains single replacement reactions using zinc and silver nitrate. Zinc replaces silver in the nitrate compound due to its higher reactivity, resulting in silver and zinc nitrate. The process is demonstrated by adding silver nitrate to solid zinc, observing the color change from light gray to dark gray, which indicates a chemical reaction.

What is a single replacement reaction?

• A reaction where compounds are broken down into simpler substances.

• A reaction where one element replaces another in a compound.

• A reaction where two elements are exchanged between compounds.

• A reaction where elements combine to form a compound.

Why does zinc replace silver in the reaction with silver nitrate?

• Zinc is less reactive than silver.

• Zinc is more reactive than silver.

• Zinc and silver have the same reactivity.

• Zinc is heavier than silver.

What are the products of the reaction between silver nitrate and zinc?

• Zinc and silver oxide

• Zinc nitrate and silver oxide

• Silver and zinc nitrate

• Silver nitrate and zinc oxide
