Explanation:
The reaction of potassium carbonate with hydrochloric acid is as follow -
Potassium Carbonate + Hydrochloric acid → Potassium Chloride + Water + Carbon Dioxide.
In the above reaction , the metal carbonate reacts with an acid to give salt , water and carbon dioxide .
The reaction is an exothermic reaction , as the release of carbon dioxide , is indicated by vigorous effervescence .
Hence ,
The temperature of the reaction increases a lot and hence the reaction is very dangerous .
Therefore , the reaction is very risky to perform.
It would be: 1 * 2 + 16 = 2 + 16 = 18
In short, Your Answer would be Option B
Hope this helps!
The correct answer would be 3.) Location of an electron
The substance that contains hydrogen that may be replaced by a metal is an acid~
