(Remember the following are diatomic: H2, N2, O2, F2, Cl2, Br2, I2) The coefficients should add up to 13. sodium carbonate + water ® sodium oxide + hydrogen carbonate (0) Na2CO3 + H2O à … b. Zn(OH)2 + CH3COOH Zn + 2CO2 +3H2O. ‍ DrBob222. a. Write balanced equation for the following reactions : (i) Zn is treated with dilute HNO 3. Add your answer and earn points. CO2 + Na2[Zn(OH)4] = H2O + Na2CO3 + Zn(OH)2 | Chemical Equation Details carbon dioxide + Sodium zincate = Water + sodium carbonate + | Elle peut se présenter sous plusieurs formes : réactifs → produits (réaction chimique irréversible ; la forme la plus courante dans les livres de chimie); la transformation n'est possible que dans un seul sens.
