The incomplete reaction Ba(ClO3)2 → ____ + 3O2 represents a decomposition reaction, where barium chlorate (Ba(ClO3)2) breaks down into barium chloride (BaCl2) and oxygen gas (O2). The other product is BaCl2, and since chlorine has seven valence electrons, barium (Ba), being in Group 2 of the periodic table, has two electrons in its outer shell.
Use the incomplete reaction to complete the activity.
Ba(ClO3)2 → ____ + 3O2
In one or two sentences, identify the type of reaction that is occurring and identify the other product. Based on the subscripts of the elements in the other product and the fact that chlorine has seven valence electrons, determine the number of electrons in barium’s (Ba) outer shell.
