By the way I love your cursive handwriting
1. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. A reaction is also considered to be a decomposition reaction even when one or more of the products are still compounds. A metal carbonate decomposes into a metal oxide and carbon dioxide gas.
2. When the lead nitrate is heated up then the lead nitrate decomposes the heat, and the nitrogen oxide appears to be the brown fumes, and then the oxygen is produced, but when the leas nitrate is heated up then it decomposes to lead nitrogen oxide, lead mono oxide and the oxygen.
3. Munitions-quality white phosphorus is generally found as a waxy, yellow, transparent solid. When exposed to air, it spontaneously ignites and is oxidized rapidly to phosphorus pentoxide. Such heat is produced by this reaction that the element bursts into a yellow flame and produces a dense white smoke.
4. Silver bromide is a photosensitive compound that decomposes when exposes to sunlight. That is the reason it is always kept in the dark bottles. The reaction of silver chloride with sunlight is also called as photolytic decomposition reaction in which the decomposition reaction carried out by sunlight.
5. When solid ammonium carbonate is heated, it decomposes to form ammonia gas, carbon dioxide gas, and water vapor, so that the solid completely disappears.
6.When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon dioxide (CO2) and water (H2O). When it undergoes combustion it produces a great amount of heat, which makes it very useful as a fuel source. Methane is a very effective greenhouse gas.
Answer:
