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.

the answer is a for all edg speedrunners ;)

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
