A) KOH (aq) + HC2H3O2 (aq) OH- (l) + HC2H3O2+ (aq) + K (s) Zn2+ (s) + CuSO4 (aq) --> ZnSO4 (aq) + Cu 2+ (aq) Since the sodium ions and the chloride ions appear on both sides of the equation they are often canceled out as spectator ions. Stoichiometric factors are derived from the coefficients in a balanced chemical equation. D) 2Al (s) + 6HBr (aq) 2AlBr3 (aq) + 3H2 (g) moles of solute = M x V Bubbles of carbon dioxide gas (CO2) are created in the reaction H2SO4 + Na2CO3 Na2SO4 + CO2 + H2O. D) mol solute/kg solvent NaCl will also dissolve in water but has no acidic protons, and thus will produce no hydronium ions in solution. $$\ce{Ba^{2+} + SO4^{2-} <=> BaSO4(s)}\tag{4}$$. A) Cu (s) + 2AgNO3 (aq) 2Ag (s) + Cu(NO3)2 (aq) E) potassium bromide, What volume (mL) of a concentrated solution of magnesium chloride (9.00 M) must be diluted to 350. mL to make a 2.75 M solution of magnesium chloride? An aqueous solution contains the following ions: Cl, F, HCO3, Mg2+, and NH+4. Therefore, this reaction has no spectator ion and hence ${H_2O}$ will be included in the ionic reaction, which is given as: $$\ce{Ba^{2+} + 2OH- + 2H+ + SO4^{2-} -> BaSO4 (s) + 2H2O(l)}$$, [1]: Complete ionic and net ionic equations, Khan Academy.
