Question

match column A and B
​

Answer 1

Answer:

1. Iron - (d) Rusts

2.magnesium - (c) Used in fireworks

3.Copper - (a) Red metal

4.Lead - (b) Used in storage battery

Explanations:

1.Rust is an iron oxide, a usually reddish brown oxide formed by the reaction of iron and oxygen in the presence of water or air moisture. ... Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called rust.

2.Magnesium – Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. Oxygen – Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur.

3.Copper, "the red metal," is one of the most electrically conductive of all the metal elements. ... It has an aesthetically pleasing red color (that easily oxidizes to a gritty green patina) that also makes the metal a favorite material for artists and architects.

4.Lead is the most efficiently recycled commodity metal and lead batteries are the only battery energy storage system that is almost completely recycled, with over 99% of lead batteries being collected and recycled in Europe and USA. The sustainability of lead batteries is compared with other chemistries.
