ores
The main element in steel is usually iron. It also contains small amounts of other substances, to improve its properties. Often it contains some carbon (not a metal), and sometimes smaller amounts of other metals.
contains enzymes and other substances
Chlorophyll contains the metal magnesium.
A metallic mineral, which contains sufficient quantities of the metal, so that the metal can be extracted efficiently, is called an ore. However, ores can also refer to minerals from which non-metallic substances can be extracted.
The ore is mixed with other substances to form a mixture called a slag. This slag is then melted to separate the useful metal from other elements present in the ore through a process called smelting. The impurities in the ore combine with the slag, allowing the pure metal to be extracted.
metal
FeCl2 is an ionic substance because it is composed of a metal (Fe) and a non-metal (Cl) and forms an ionic bond. ReCl6 is also an ionic substance because it contains a metal (Re) and a non-metal (Cl) and forms an ionic bond.
Co2

Nylon is a synthetic polymer. It contains no metal.
There are 3 main substances that can be recycled. These 3 substances are paper products, metal products, and glass products.
Two common substances that cause corrosion are oxygen and moisture. When these substances come into contact with metal, they can cause a chemical reaction that leads to the breakdown of the metal over time.
