2. For the reaction of aqueous hydrochloric acid with the hypothetical aqueous hydroxide, M(OH)2, write three separate equations; one showing the full reaction with full formula, one showing all the ions present in solution, and one showing the net ionic equation. In each case balance the equations that you write and be sure to show state symbols clearly. (Assume that the salt produced is soluble). (6) FULL:

3. Consider the following reactants being brought together in aqueous solution. For each pair, decide the following, and then fill in the table accordingly. (25)
?
Is there are reaction? Write Y for yes or N for no.
?
If there is a reaction, write a full equation, if there is no reaction, write NR.
?
If there is a reaction classify in two ways by choosing two types from the
following list that apply. If there is no reaction write NR.
Precipitation, acid-base, REDOX, single displacement, double
displacement, combination, decomposition, combustion.
?
If there is no reaction briefly explain why. If there is a reaction write R.
