What happens when the products of this reaction: B+LiN03+C+O2---> interact with air?

Solution.

$$\mathrm {B} + \mathrm {L i N O} _ {3} + \mathrm {C} + \mathrm {O} _ {2} =$$

Since it is not said under what conditions this reaction was carried out, among the above substances, only C and O₂ react with each other. Other substances do not react with each other due to the non-specificity of this reaction (for example, the temperature must be very high when fusing B₂O₃ and C). During the reaction process, the products will be B, LiNO₃ and CO₂. In air, CO₂ will evaporate, and boron will turn into B₂O₃ (4B+3O₂ = 2B₂O₃). LiNO₃ will diffuse within 10-15 minutes.

Answer:

B₂O₃, LiNO₃

During the reaction process, the products will be B, LiNO₃ and CO₂. In air, CO₂ will evaporate, and boron will turn into B₂O₃ (4B+3O₂ = 2B₂O₃). LiNO₃ will diffuse within 10-15 minutes.
