boric oxide

[dg_5021]

When I react CO2 with CaO I get CaCO3. If I react boric oxide with CO2 would it react similarly like the other one?

Boric oxide (B2O3) may be amphoteric. If it is, then you might expect a similar reaction ...but if it's only an acidic oxide, I doubt that you'll have a reaction.

I'm probably wrong on this...let's wait for the experts to come along...

so would I get B2CO4?

[Pyrovus]

Boric oxide's acidic, so you aren't likely to get any reaction, and even if you did the product would be unstable and would easily decompose back to boric oxide and carbon dioxide.

Pyrovus is right. I have no knowledge on boric oxide , but the nearest compound is boric acid, \displaystyle H_3BO_3, or better written as \displaystyle B(OH)_3. However, borax, \displaystyle Na_2B_4O_7 is a cage-framework polyboric oxide. If you react this one with carbon dioxide, sodium carbonate will probably formed, resulting a cleavage inside the cage.

so i wouldn't get similar react I would just get no reaction?

You'd better look up Lux' Acid and Base concept; non protonic compounds (very generally, oxides) can behave acid or base according to some rules. In here, I presume that carbon dioxide is the acid, and boric oxide is also acidic; that's why I am doubtful about any reaction, like Gokul.

Boric oxide (B2O3) may be amphoteric....
Boron is amphoteric:

"MATERIAL OVERVIEW

"Characteristics: Nonmetallic element, black, hard solid; brown, amorphous powder; crystals. Highly reactive. Soluble in concentrated nitric acid and sulfuric acid; insoluble in water, alcohol, and ether. High neutron absorption capacity. Low toxicity. Amphoteric...."

However, I don't think that necessarily means that PARTICULAR oxide will form both acids and bases.

In building up a compound, elemental properties drastically change. So we cannot devise a logic from there. Look at the example of water; hydrogen is a flammable gas, oxygen is a ignitor gas; water is a extinguisher.
