The decomposition of limestone may be spontaneous if it also does not require continual input of energy.
Under most circumstances sulphur burns to give SO2. Limestone will not burn but can decompose to leave CaO. Heated together in the presence of air, another product might be CaSO3. Without defining what constitutes a product, defining a by-product is impossible.
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
Dilute hydrochloric acid (HCl) is used, and this fizzes due to the presence of calcium carbonate (CACO3) in limestone
When magnesium is burnt in the presence of oxygen, the magnesium and oxygen combine to form the compound magnesium oxide. Therefore, this would be a combination combustion.
pure nitric acid is colourless and unstable and decomposes slightly even at ordinary temperatures and in the presence of sunlight. The decomposition results in formation of reddish brown nitrogen dioxide which remains dissolved in the acid thus imparting a slight yellowish brown colour.
Cardboard, unless it is coated with a wax finish, is bio-degradable. It will decompose in approximately 2-months. Moisture, heat, and the presence of other biological materials will affect decomposition.

light will produces heat which will speed up the rate of decomposition.
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
A person can decompose in any kind of hermetically sealed coffin because of the presence of anaerobic microorganisms (bacteria thriving without the presence of oxygen) and of mould.
The ozone decomposes in the presence of UV-B. It has got large energy.
what was the main difference between doves and hawks regarding the US presence in Vietnam
what was the main difference between doves and hawks regarding the US presence in Vietnam
If regarding presence: absent If regarding time: precedent
It depends on what type of bone. A human bone would take about 8 years in a area like Mexico, while it would take 80 years in a cold environment like Canada. It depends on the contents of the bone and the environment it is in.
That the dustbin gets emptied in a landfill and that the compost heap returns decomposed materials back to the soilis a reason why putting household waste in the compost heap takes precedence over putting it in the dustbin.Specifically, household waste can decompose in a compost heap or a local landfill. But the heap is more environmentally friendly since the materials decompose through aerobic decomposition, or break-down in the presence of air. The landfill is the site of anaerobic decomposition, or break-down in the absence of air, and therefore results in an increase in atmospheric greenhouse gases what with the methane thereby produced.
This past week I visited a limestone quarry that has been mining limestone in one place for 40 years. In that time, they will have mined millions of tons of limestone. Usually nearly ALL the rock is limestone, so the answer will depend on the size (area) of the quarry, how deep you can mine, and presence of any "trash" rock.
