QUESTION 5 QUESTION 5 A brisk effervescence is seen when diluted hydrоchlоric аcid (HCl) reаcts with sоdium cаrbonate (Na2CO3). The balanced equation for the reaction is: Na2CO3(s) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l) 5.1 Write down the FORMULA of the substance that causes the brisk effervescence that is seen.
