A decomposition reaction needs the addition of a catalyst or heat to proceed. For instance hydrogen peroxide will break down into water and oxygen gas in the presence of a catalyst; and calcium carbonate will break down into calcium oxide and carbon dioxide gas when heated.

What kind of symbol is used to show that heat is needed in decomposition reaction?

There is no symbol that will show weather or not heat is needed in a decomposition reaction.


If you break a compound down by using heat it is called?

Solids melt on heating. A2. But if you are thinking of the destruction of the material, perhaps pyrolysis is what you seek.


How does presence of light affect the rate of decomposition?

light will produces heat which will speed up the rate of decomposition.


Why is decomposition of vegetable matter into compost considered to be exothermic?

This is because, all thermal decomposition ( and all decomposition processes ) is an exothermic process. Well, if you need a full explanation, here goes. More energy is given off to form bonds then taken in to break bonds hence it is an exothermic reaction. Also, decomposition gives off heat energy.


What does the decomposition of organic matter by heat describe?

Pyrolysis


Is decomposition possible without heat?

Heat is a relative term. Hot, as in cooking or a very warm day, or room temperature. Freezing can be 32 to -32. Decomposition usually describes something being eaten by microbes that turn the large molecules into smaller ones, producing smelly waste gas, and such. Turning something into a pile of goo. The warmer it is, the quicker most bacteria can do their job. Room temperature has heat, not necessarily added heat. In a home freezer the bug will work slower, but some can still live and eat in.


What is it called when heat breaks up a substance?

What should you put in a casket with a dog for decomposition?

There is no need to put anything, decomposition will happen naturally.


When you heat a chemical compound does the heat destroy some of the mass?

The mass may be modified by oxidation or thermal decomposition.


Does heat help decomposition?

Yes, heat can help speed up the decomposition process by increasing the activity of microorganisms that break down organic matter. However, extremely high temperatures can also kill off these microorganisms and slow down decomposition. The optimal temperature for decomposition usually ranges between 90-140°F (32-60°C).


Why is decaying matter warm?

The chemical processes involved in decomposition generate heat.
