Based on your answer, would you expect the rotational modes of air molecules to contribute to the heat capacity of air at room temperature? = 0.00504 mol H2SO4 Is Koestler's The Sleepwalkers still well regarded? 0.00202 mol Ag+ x (1 mol Cl-/1 mol Ag+ ) x (35.45 g Cl-/1 mol cl-) = 0.0072 g Cl- c) Only barium nitrate precipitates A 0.355 M K2SO4 solution can be prepared by ________. b) Pb(NO3)2 (aq) and Fe(s) 1) Here is the complete ionic equation: 2K+(aq) + 2Al3+(aq) + 8OH-(aq) + 2H+(aq) + SO42-(aq) ---> 2Al(OH)3(s) + 2K+(aq) + SO42-(aq) + 2H2O() Note that the sulfuric acid is treated as fully dissociated. In many cases a complete equation will be suggested. We therefore write the state symbol (s) after the compound that precipitates out of solution.If you are unsure if a compound is soluble when writing net ionic equations you should consult a solubility table for the compound._________________Important SkillsFinding Ionic Charge for Elements: https://youtu.be/M22YQ1hHhEYMemorizing Polyatomic Ions: https://youtu.be/vepxhM_bZqkDetermining Solubility: https://www.youtube.com/watch?v=5vZE9K9VaJIMore PracticeIntroduction to Net Ionic Equations: https://youtu.be/PXRH_IrN11YNet Ionic Equations Practice: https://youtu.be/hDsaJ2xI59w_________________General Steps:1.
