Balance each element on each side of the reaction arrow by adding coefficients to the reactants and products. Spectatorsprovide encouragement to the team and generate enthusiasm. They do not remain as Cl2 (that would be elemental chlorine; these are chloride ions), and they do not stick together to make Cl2 or Cl22. Liquid silicon tetrachloride is reacted with very pure solid magnesium, producing solid silicon and solid magnesium chloride. The Na would have a +1 charge and, the Cl would have a -1 charge, 2 (-1) charges would give an overall -2 charge which would not produce an overall 0 charge. What remains when the spectator ions are removed is called the net ionic equation, which represents the actual chemical change occurring between the ionic compounds: It is important to reiterate that the spectator ions are still present in solution, but they do not experience any net chemical change, so they are not written in a net ionic equation. In the case of a single solution, the last column of the matrix will contain the coefficients. AlBr3 reacts with Na3PO4 to form NaBr and, A: Bases produce OH- ions in solution and acids produce H+ ions when dissolved in water.
