Chapter 4, Problem 4.29E
(De Morgan’s Laws)In this chapter, we discussed the logical operators &&, Ó� Ó�, and !. De Morgan’s Laws can sometimes make it more convenient for us to express a logical expression. These laws state that the expression! (condition1 && condition2) is logically equivalent to the expression (! condition 1 Ó� Ó� condition2). Also, the expression condition1 Ó� Ó� condifion2 is logically equivalent to the expression (condition1 && ! condition2). Use De Morgan’s Laws to write equivalent expressions for each of the following, and then write a

INTRODUCTION:
In chemistry, neutralization occurs when an acid and a base react with each other. Most chemistry occurs in water (that is, is aqueous); under these circumstances, neutralization leads to water with no excess hydrogen or hydroxide ions present. Neutralization can most simply be expressed as
acid + base → salt + water
For example,
HCl + NaOH → NaCl + H2O
The stoichiometry of the reaction depends on how much hydrogen ion and hydroxide ion each reactant provides. In this case, each molecule of HCl provides one hydrogen ion, and each molecule of NaOH provides one hydroxide ion. The one hydrogen and one hydroxide ion combine to form one molecule of water.
For this assignment, suppose that you have been presented with several solutions of hydrochloric acid (HCl) and some of the most popular bases for wastewater treatment: magnesium hydroxide (Mg(OH)2), calcium carbonate (CaCO3), calcium oxide (CaO), sodium bicarbonate (NaHCO3), sodium hydroxide (NaOH), and ammonia…

(i) Some old dogs can learn new tricks.
(ii) No rabbit knows calculus.
(iii) Every bird can fly.
(iv) There is no dog that can talk
(v) There is no one in this class who knows French and Russian
