Question

Hello, I am not sure what I am doing wrong.

Could someone please explain :)

Thank you!

The mineral dolomite contains magnesium carbonate. This reacts with hydrochloric acid. MgCO3(s) + 2 HCl(aq) + CO2(g) + MgCl, (aq) + H20(0) a. Write the net ionic equation for this reaction and identify the spectator ions. (If needed, use H3O+ for the hydronium ion. Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (ag) or (3). If a box is not needed, leave it blank.) y Mgcoz -CO, + 2H+ (aq) vx + o v 9 vv +Me2 69) vv - H20 ° * b. What type of reaction is this? precipitation acid-base gas-forming oxidation-reduction

Answer 1

H+ does exact alone it exists in form of H3O+
