What happens during thermal decomposition?

Answer 1

Thermal decomposition refers to the process of a substance decomposing as a result of being exposed to heat. The heat typically breaks the chemical bonds in the substance, which leads to the decomposition.

Answer 2

During thermal decomposition, a compound is broken down into simpler substances when it is heated to high temperatures. This process usually involves the breaking of chemical bonds within the compound, leading to the formation of different products. The decomposition products can include elements, smaller molecules, or other compounds, depending on the chemical composition of the initial substance.

Answer 3

It is the break down of a compound by heat; heat is required to break chemical bonds in the compound and so the term 'thermal.'

-H2CO3 → H2O + CO2

Carbonic acid → Water + Carbon dioxide

(Heat applied)

-CaCO3→CaO + CO2

(Heat applied)

Calcium carbonate → Calcium oxide + Carbon dioxide

Answer 4

the reaction in which a single compound breaks down to give two or more simpler substances are called decomposition reaction.

there are three types of decomposition reactions

1.thermal decomposition

2.electrolytic decomposition

3.photolytic decomposition

examples:-

CaCO3 (arrow) CaO + O2

2NaCl (arrow) 2Na + Cl2

2AgCl (arrow) 2Ag + Cl2

Answer 5

If in a reaction 2 or more than 2 substances are obtain by decomposition of 1 substance by heating, then the reaction is called thermal decomposition reaction

For eg. CaCo3 give rise to CaO + CO2 (in this reaction lime stione is heated, calcium oxide & carbon dioxide r obtained due to decomposition reaction. Hence it is an eg. of thermal decomposition reaction.)

Answer 6

it is the spliting of something by heat its carbonate element

Answer 7

During thermal decomposition, compounds absorb energy and are broken apart.

Answer 8

Zinc nitrate decomposes on heating to give zinc oxide, nitrogen dioxide and oxygen:

Zn(NO3)2 (s) -----> 2ZnO (s) + 4NO2 (g) + O2 (g)

Answer 9

During thermal decomposition a big molecule is transformed in smaller molecules

Answer 10

it is used to measure a straight line
