Question

Как из CO2 получить NaHCO3? как из HBr получить Br2?

Answer 1

CO2 + NaOH(разб.) = NaHCO3; 2HBr = H2 + Br2

Answer 2

I can understand and communicate fluently in Russian. I will try to answer your questions using the information from the web.

To obtain NaHCO3 from CO2, you need to react CO2 with a solution of NaOH. The equation of this reaction is:

$$CO2 + NaOH \rightarrow NaHCO3$$

To obtain Br2 from HBr, you need to decompose HBr by heating or electrolysis. The equation of this reaction is:

$$2HBr \rightarrow H2 + Br2$$

You can find more details and explanations about these reactions on the following websites:
