No not really, metals rust. However, rust can be considered metal decomposition (kind of).
depends on the conditions they are exposed to and also the type of metal
Metals are not decomposed by heating. Some metals burn, as magnesium.
If the nitrates are of alkali metals, they decompose into Nitrites and Oxygen:NO3- --Δ--> NO2-+ O2If the nitrates are of other metals, they decompose into Metal oxides, Nitrogen dioxide and Oxygen:NO3- --Δ--> O2- + NO2 + O2
Metals are inorganic, they don't decompose. They might change form by bonding with other elements (e.g. rusting) but metals don't "decompose".
No... while metals are recyclable, they do not decompose like vegetation. They need to be processed and refined.
They decompose all dead animals.
Metals do not decompose. They rust. In a way, you can consider rust a metal;s form of decomposition, but not really.... Actually, only iron rusts. Many metals are oxidized which results in rust, patina, etc. And the length of time varies with environmental conditions and the type of metal.
Yes. All animals decompose when they die.
Animals aren't the only ones that decompose, all living organisms decompose as well. For example, trees aren't animals, but they do decompose because they are a living organism.
There are some waste products that take a very long time to decompose in a landfill. Thus, they should be recycled, instead of simply thrown away. For example, an aluminum can takes around 100 years to decompose.
NOT all metals are magnetic
All metals are chemical elements.
