Mass of Wire Wool

The video tutorial demonstrates an experiment to observe the effects of combustion on wire wool. It begins by introducing the materials needed: wire wool, a blowtorch, a digital balance, a metal bucket, and a compressed air pump. The experiment involves burning the wire wool and measuring the mass before and after combustion, showing an increase in mass due to the formation of iron oxide. The tutorial explains the combustion process, highlighting the role of heat, oxygen, and fuel. It compares the burning of wire wool to solid iron, emphasizing the larger surface area of wire wool that facilitates combustion. The video concludes by explaining the chemical reaction where oxygen combines with iron, resulting in a mass increase.

Why is wire wool used instead of solid lumps of iron in this experiment?

What happens to the mass of the products when wire wool is burned?

Describe the chemical reaction that occurs when metallic iron burns.
