Answer
a. $Ba(OH)_2$
b. $HI$
c. $HNO_3$
d. $Sr(OH)_2$
e. $HC_2H_3O_2$
f. $HClO$
Work Step by Step
a. Since Barium is from the second column of the periodic table, it forms the $Ba^{2+}$ ion. Thus, it needs two hydroxide ions $OH^-$ to balance the total charge: $Ba^{2+} + 2OH^- \longrightarrow Ba(OH)_2$
b. See table 11.1 (Page 401)
c. See table 11.1 (Page 401)
d. Since Strontium is from the second column of the periodic table, it forms the $Sr^{2+}$ ion. Thus, it needs two hydroxide ions $OH^-$ to balance the total charge: $Sr^{2+} + 2OH^- \longrightarrow Sr(OH)_2$
e. See table 11.1 (Page 401)
f. As we can see on the third paragraph of the 'Naming acids' section, $HClO$ is named hypochlorous acid.
