d. Is the reaction spontaneous as written? 17.7: Electrolysis - Chemistry LibreTexts The overall chemical equation for the reaction shows each reactant and product as undissociated, electrically neutral compounds: 2AgNO3(aq) + K2Cr2O7(aq) Ag2Cr2O7(s) + 2KNO3(aq) 1). Molecular weight AgNO3 = 108+14+3*16=170(g/mol) To determine whether a precipitation reaction will occur, we identify each species in the solution and then refer to Table \(\PageIndex{1}\) to see which, if any, combination(s) of cation and anion are likely to produce an insoluble salt. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. For charge to be conserved, the sum of the charges of the ions multiplied by their coefficients must be the same on both sides of the equation. This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here! The reaction was stopped before all the nickel reacted, and 59.5 g of solid metal (nickel and silver) is present. Silver nitrate reacts with nickel metal to produce silver metal The anode is connected to a voltmeter with a wire and the other terminal of the voltmeter is connected to a silver electrode by a wire. Na2SO3 +2HCl (arrow) 2NaCl + SO2 +H2O Solutions of silver nitrate and zinc nitrate also were used. I'm sure this is often requested o. Nothing could be further from the truth: an infinite number of chemical reactions is possible, and neither you nor anyone else could possibly memorize them all. From the information given, we can write the unbalanced chemical equation for the reaction: \[\ce{Ba(NO_3)_2(aq) + Na_3PO_4(aq) \rightarrow Ba_3(PO_4)_2(s) + NaNO_3(aq)} \nonumber \]. No concentrations were specified so: \[\ce{Cr}(s)\ce{Cr^3+}(aq)\ce{Cu^2+}(aq)\ce{Cu}(s). Experts are tested by Chegg as specialists in their subject area. The cell notation (sometimes called a cell diagram) provides information about the various species involved in the reaction. When these solutions are mixed, the only effect is to dilute each solution with the other (Figure \(\PageIndex{1}\)). We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Characteristic Reactions of Ni Nickel (II) ion forms a large variety of complex ions, such as the green hydrated ion, \ce { [Ni (H2O)6]^ {2+}}. I need help with describing the process of obtaining the following question in detail with a balanced equation and all the calculations. Write the overall chemical equation, the complete ionic equation, and the net ionic equation for the reaction of aqueous silver fluoride with aqueous sodium phosphate to give solid silver phosphate and a solution of sodium fluoride. The equation for the reduction half-reaction had to be doubled so the number electrons gained in the reduction half-reaction equaled the number of electrons lost in the oxidation half-reaction.
