Write balanced formula unit, total ionic and net ionic equations for the following reactions. As defined in the text, identify the "gas evolution" reactions among the following: ... All the above ions are in the net ionic equation. CaO is a compound made of calcium ions (Ca 2+) and oxide ions (O 2–), so CaO is calcium oxide. Solution: A Aluminum is an active metal that lies above silver in the activity series, so we expect a reaction to occur. (take the subscript for the ion (if it has one) and multiply it by the coefficient. ; Solution. This type of reaction is called a precipitation reaction, and the solid produced in the reaction is known as the precipitate.You can predict whether a precipitate will form using a list of solubility rules such as those found in the table below. Before you do anything, you are going to need 4 lines to do this. ��ࡱ� > �� g i ���� f �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������� � �� �% bjbjQFQF 7j 3, 3, � �� �� �� � D D � � � � � ���� � � � � � W \ � �( L � � � � � � � � {( }( }( }( }( }( }( $ H, � �.
