For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. H2(g) + Cl2(g) --> 2HCl(g) Write a sentence that completely describes the chemical reaction represented by this balanced equation. Answer to: Identify the equation as a molecular equation, a complete ionic equation, or a net ionic equation. Write a net ionic equation for the reaction of CaCO3(s) with a strong acid. Ionic charges are not yet supported and will be ignored. You can use parenthesis or brackets []. Then make the Cl equal on both sides by putting a 2 in front of HCL. 6 years ago. Replace immutable groups in compounds to avoid ambiguity. CaCO3(s) + HCl(aq) --> CaCl2(aq) + CO2(g) + H2O. Start off by making the Ca equal on both sides, which is fortunately already done. Compound states [like (s) (aq) or (g)] are not required. CaCO3 (s) + 2 HCl (aq) --> CaCl2 (aq) + H2CO3 (aq) H2CO3, carbonic acid, is a weak acid and unstable in solution at high concentrations. Replace immutable groups in compounds to avoid ambiguity. In simple word, a chemical reaction is represented by the ionic reaction equation, if the ions of each element are participating in the reaction and produces the product. CaCO3(s) + 2HCl --> CaCl2(aq) + CO2(g) + H2O. HNO3(aq) + CaCO3(s) ----> Ca(NO3)2(aq) + H2O(l) + CO2(g)Just Balance (c) - (e)(c). Problem: CaCO3 (s) + HCl (aq) → CaCl2 (aq) + CO2 (g) + H2O (l)Consider the unbalanced equation above. Ionic charges are not yet supported and will be ignored. How To Balance Equations Relevance. Answer Save. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. The ionic equation requires you to break these compounds into their ions if they exist in solution: - note: calcium carbonate is insoluble whilst sodium chloride is not 2Na^+ + CO3^2- + Ca^2+ + 2Cl^- ---> CaCO3(s) + 2Na^+ + 2Cl- Calcium carbonate dissolves into Ca(2+) and carbonate (CO3)(2-) ions. CaCO3(s) + 2HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l) CaCO3(s) + 2H+ --> Ca2+ + CO2(g) + H2O (l) (net ionic);) James. 1 Answer. If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation … Ok this is the net ionic equation for this reaction: Hydrochloric acid and calcium carbonate: 2H+CaCO3 ---Ca+ CO2+ H20 Don't forget to put the charges to the elements and compounds. Hydrochloric acid dissolves into H(+) and Cl(-). Lv 6. Zn(s) + HCl(aq) ----> H2(g) + ZnCl2(aq)(b). Start off with the original equation. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. Please include phases. Write a balanced equation for the production of HCl gas from its elements. What is the concentration of the original hydrochloric acid solution if 91.5 mL of HCl reacts with 3.72 g of calcium carbonate? Question: (a).
