Question

1. an investigation of the compounds listed in the table most likely would lead to the observation that which compound has the most properties in common with hbr?

a. naoh
b libr
c. hcl
d. br

1. which equation shows the outcome of a salt dissolved in water?

a. na+ + cl- → nacl
b. naoh → na+ + oh-
c. hcl → h+ + cl-
d. nacl → na+ + cl-

Explanation:

Step1: Analyze Question 1

HBr is an acid. Acids ionize to produce \(H^{+}\) ions. Looking at the options, \(HCl\) is also an acid (as per the table, acids like \(HCl\), \(HBr\), \(HI\) ionize to give \(H^{+}\) ions). \(NaOH\) is a base (\(NaOH
ightarrow Na^{+}+OH^{-}\)), \(LiBr\) is a salt (\(LiBr
ightarrow Li^{+}+Br^{-}\)), and \(Br\) is an element (not a compound in the context of acid - base - salt classification).

Step2: Analyze Question 2

Salts ionize in water. The table shows that for salts like \(NaCl\), \(LiBr\), \(KI\), the ionization reaction is of the form \(salt
ightarrow cation + anion\). Option A is the reverse of salt formation (not dissolution). Option B is the ionization of a base (\(NaOH\)). Option C is the ionization of an acid (\(HCl\)). Option D (\(NaCl
ightarrow Na^{+}+Cl^{-}\)) is the ionization of a salt (\(NaCl\) is a salt as per the table)

Answer:

1. C. \(HCl\)
2. D. \(NaCl

ightarrow Na^{+}+Cl^{-}\)
