Which equation is a decomposition reaction? Li2CO3 Right arrow. Li2O + CO2 Zn + HCl Right arrow. ZnCl2 + H2 Na2O + CO2 Right arrow. Na2CO3 C6H12O6 + O2 Right arrow. CO2 + H2O

Li₂CO₃ ⇒ Li₂O + CO₂ is a decomposition reaction.

Explanation:

In a decomposition reaction, a single substance decomposes, producing two or more different substances. In other words, in this type of reaction two or more substances are formed from a compound. The atoms that form a compound separate to give the products according to the formula:

AB → A + B

It can occur spontaneously, or be aided by a catalyst, heat, or electrolysis.

In this case:

Li₂CO₃ ⇒ Li₂O + CO₂ It is a type of chemical reaction in which a single compound decomposes into two or more compounds. So it is a decomposition reaction.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
