CO2(g) + 2KOH(s) --> H2O(g) + K2CO3 (s) Express your answers numerically in kJ. Na2CO3(s)-->Na2O(s) +CO2(g) solid sodium carbonate is heated to give solid sodium oxide and carbon dioxide gas. b. 15.8 mol. In many cases a complete equation will be suggested. Previous question Next question Get more help from Chegg. 83% (302 ratings) Problem Details. Expert Answer . The equation for the thermal decomposition of KHCO3 is: 2KHCO3(s) ---> K2CO3(s) + CO2(g) + H2O(l) Can someone help me to construct an energy cycle to link this reaction with the two reactions of HCl (aq) with KHCO3 and K2CO3? Problem: CaCO3 (s) + HCl (aq) → CaCl2 (aq) + CO2 (g) + H2O (l)Consider the unbalanced equation above. What is the concentration of the original hydrochloric acid solution if 91.5 mL of HCl reacts with 3.72 g of calcium carbonate? 1.58 mol. Reaction stoichiometry could be computed for a balanced equation. ‘’a. CaCO 3 (s) + HCl (aq) → CaCl 2 (aq) + CO 2 (g) + H 2 O (l) Consider the unbalanced equation above. Expert Answer . Chemistry Part A Calculate the standard enthalpy change for the reaction 2A+B --->2C +2D Use the following data: Substance Delta H(kJ/mol) A -263 B -391 C +203 D -523 Express your answer in kilojoules. 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. 2KHCO3(s) K2CO3(s) + CO2(g) + H2O(l) How many moles of potassium carbonate will be produced if 311 g of potassium hydrogen carbonate are heated?
