Which reaction would it be possible to calculate (Triangle H)?
Aqueous solutions of calcium chloride and sodium hydroxide react to form solid calcium hydroxide. The balanced net ionic equation is: A) Ca+2(aq) + 2OH-(aq) + 2Na+(aq) + 2Cl-(aq) → Ca(OH)2(s) B) Ca+2(aq) + 2OH-(aq) + Na+(aq) + Cl-(aq) → Ca(OH)2(s) C) Ca+2(aq) + 2OH-(aq) → Ca(OH)2(s) D) CaCl2(aq) + 2NaOH(aq) → CaOH(s) + NaCl(aq) E) CaCl2(aq) + 2NaOH(aq) → Ca(OH)2(s) + 2NaCl(aq)
Given the following equation: 2H3PO4 + 3Mg(OH)2 → 6 H2O + Ca3(PO4)2 + 450.8 kJ If 300 mL of 0.75 mols/L phosphoric acid solution, H3PO4, is mixed with 25.0 g of magnesium hydroxide, Mg(OH)2, predict the amount of energy released Note: the sign (-/+) is not relevant to the question. Your answer should follow the format: a) mols of H3PO4 b) maximum energy released if all of the H3PO4 reacts (with units) c) mols of Mg(OH)2 d) maximum energy released if all of the Mg(OH)2 reacts (with units) e) based on your answer to (b) and (d), how much energy will be released by this reaction based on the quantities of reactants indicated.
