Answer:
V
Explanation:
Firstly let’s list the names of the atoms
1. Sodium
2. Magnesium
3. Aluminum
4. Oxygen
5.Chlorine
Generally, anions have greater electron affinity than cations. Hence, they have more positive values for this electron affinity. This means that the higher the electron affinity, the greater its positive value
Electron affinity increases across a period. Thus, it is expected that chlorine has the highest value
Answer:
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:
co+ o2+ 2co2 is not balanced reaction
