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...
please solve for me as always! Thanks you very much. Exercise 5.71 9 of 10 > Review Constants Periodic Table Part A The zinc within a copper-plated penny will dissolve in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can get to the zinc). The reaction between the acid and the zinc is 2H+ (aq) + Zn(s) + H2(g) + Zn²+ (aq). When the zinc in a certain penny dissolves, the...
