Dec 6, 2018 · Sodium Oxide (Na2O) can react with hydrochloric acid (HCl) to produce sodium chloride (NaCl) and water (H2O) according to the following equation: Na2O + 2HCl -> 2NaCl + H2O How many total atoms are present before and after the reaction? A) 2 before and 2 after B) 3 before and 3 after C) 5 before and 5 after D) 7 before and 7 after

Nov 7, 2023 · Doing so, we find that the balanced chemical equation is 6 Na2O + P4O10 = 12 Na3PO4. To explain further, in the product Na3PO4, there are 3 sodium (Na), 1 phosphorus (P), and 4 oxygen (O) atoms. To match this on the reactants side, we need six molecules of Na2O (giving us 12 Na and 6 O atoms) and one molecule of P4O10 (adding another 4 P and 10 ...

The standard molar enthalpy of formation for Na2O(s) can be calculated by taking the sum of the standard enthalpy of formation of Na2O2(s) (-505 kJ/mol) and the enthalpy change for the reaction Na2O(s) + 1/2 O2(g) to Na2O2(s) (+89.0 kJ/mol), resulting in -416 kJ/mol for Na2O(s).
