Question: Which type of reaction is \( 2Cu{{(N{{O}_{3}})}_{2}}\to 2CuO+4N{{O}_{2}}+{{O}_{2}}? \)...

Which type of reaction is 2Cu(NO3)2→2CuO+4NO2+O2?2Cu{{(N{{O}_{3}})}_{2}}\to 2CuO+4N{{O}_{2}}+{{O}_{2}}?

Explanation

Solution

A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.

Complete answer:
The thermal breakdown of copper(II) nitrate is described by the reaction you were given. A decomposition reaction is distinguished by the presence of a single reagent and many products. Simply defined, a decomposition reaction occurs when one chemical component is broken down into smaller pieces, resulting in the formation of new chemical species. Anhydrous copper(II) nitrate undergoes thermal breakdown in this scenario, yielding oxygen gas, NO2N{{O}_{2}} , and copper(II) oxide, CuO.
Hence 2Cu(NO3)2→2CuO+4NO2+O22Cu{{(N{{O}_{3}})}_{2}}\to 2CuO+4N{{O}_{2}}+{{O}_{2}} is a thermal decomposition reaction.
The chemical decomposition produced by heat is known as thermal decomposition. The temperature at which a material chemically decomposes is known as its decomposition temperature. Heat is necessary to break chemical bonds in the molecule being decomposed, therefore the reaction is generally endothermic. A positive feedback loop is produced if decomposition is sufficiently exothermic, resulting in thermal runaway and perhaps an explosion or other chemical event.
Copper nitrate may be used to produce nitric acid by burning it until it decomposes and then transferring the fumes directly into water, taking advantage of its reactivity. This approach is comparable to the Ostwald process' last phase. The following are the equations:
2 Cu(NO3)2 → 2 CuO + 4 NO2 + O22\text{ }Cu{{(N{{O}_{3}})}_{2}}~\to \text{ }2\text{ }CuO\text{ }+\text{ }4\text{ }N{{O}_{2}}~+\text{ }{{O}_{2}}
3NO2 + H2O → 2HNO3 + NO3N{{O}_{2}}~+\text{ }{{H}_{2}}O\text{ }\to \text{ }2HN{{O}_{3}}~+\text{ }NO
Hence thermal decomposition is correct.

Note:
Copper(II) nitrate has a number of uses, the most important of which being its conversion to copper(II) oxide, which is employed as a catalyst in a number of organic chemical processes. Its solutions are utilised in textiles and as metal polishing agents. Some pyrotechnics contain copper nitrates. Chemical voltaic cell processes are frequently shown in school laboratories. It's used in a variety of ceramic glazes and metal patinas.
