Most metals do not decompose in the traditional sense, but rather corrode or tarnish over time due to exposure to air or water. Some metals, like alkali metals, can react violently with water, leading to decomposition into their elemental components. Additionally, highly reactive metals such as magnesium and aluminum can decompose at high temperatures through a process known as thermal decomposition.
When heated, metallic chlorate decomposes into metal chloride and oxygen gas. The metal chloride is usually a solid while the oxygen gas is released as a byproduct.
Zinc oxide can be obtained by heating zinc nitrate.
Experimentally to prove that, capture the gas and pass it through lime water. If the lime water turns milky then the gas is CO2 . Or an example of equation for decomposition of a metal carbonate is :- MgCO3 + heat ------> MgO + CO2
MgCO3 --> MgO + CO2(g) Magnesium oxide and gaseous carbon dioxide
Yes, it decomposes into silver and bromine
the metal carbonate decomposes into a metal oxide and carbon dioxide

When tin oxide (SnO) decomposes upon heating, it forms tin metal (Sn) and oxygen gas (O2) as the products. The reaction can be represented as: 2SnO -> 2Sn + O2.
The Metal hydroxides are strong base, therefore metal hydroxide decomposes on heating to form metal oxide and water.
The decomposition reaction is:MgCO3 = MgO + CO2
Mercuric oxide decomposes upon heating to give off mercury and oxygen.
Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.
The amount of sodium metal produced can be calculated using the law of conservation of mass. The total mass of products (nitrogen gas and sodium metal) should equal the initial mass of sodium azide. In this case, 500g of sodium azide decomposes to form 323.20g of nitrogen gas and 176.80g of sodium metal. Therefore, 176.80g of sodium metal is produced.
