Before handing in this Lesson, be sure to hand in and use the feedback from Lesson 13 and Lesson 14. 1. a. Complete each of the following equations below. Predict the $\mathrm{pH}$ range (acid, base or neutral) for each of the solutions that will form. $\begin{array}{l}{\mathrm{CaO}}_{(s)}+{\mathrm{H}}_2{\mathrm{O}}_{(i)}?\\ {\mathrm{NO}}_{2(0)}+{\mathrm{H}}_2{\mathrm{O}}_{(}?\end{array}$ b. Explain your prediction. (6 mark total) 2. a. Balance each of the following neutralization reactions: (3 marks) $\begin{array}{l}{\mathrm{H}}_3{\mathrm{PO}}_{4(\mathrm{aq})}+{\mathrm{NaOH}}_{(\mathrm{aq})}?{\mathrm{Na}}_3{\mathrm{PO}}_{4(\mathrm{aq})}+{\mathrm{H}}_2{\mathrm{O}}_{(1)}\\ {\mathrm{H}}_2{\mathrm{S}}_{(\mathrm{aq})}+{\mathrm{NaOH}}_{(\mathrm{aq})}?{\mathrm{Na}}_2{\mathrm{S}}_{(\mathrm{aq})}+{\mathrm{H}}_2{\mathrm{O}}_{(1)}\\ {\mathrm{HF}}_{(\mathrm{aq})}+{\mathrm{NaOH}}_{(\mathrm{aq})}?{\mathrm{NaF}}_{(\mathrm{aq})}+{\mathrm{H}}_2{\mathrm{O}}_{(\mathrm{l}}\end{array}$ b. Use the molar ratio to determine how many moles of base are needed to neutralize 5 moles of acid for each of the above reactions. (3 marks) 3. Write a balanced equation for the following neutralization reaction. ( 6 marks) a. ${\mathrm{HNO}}_{3(\mathrm{aq})}+{\mathrm{KOH}}_{(\mathrm{aq})}?$ b. ${\mathrm{H}}_2{\mathrm{SO}}_{4(\mathrm{aq})}+\mathrm{Ca}(\mathrm{OH}{)}_{2(\mathrm{aq})}?$ c. ${\mathrm{HClO}}_{3(\mathrm{aq})}+\mathrm{Ba}(\mathrm{OH}{)}_{2(\mathrm{aq})}?$ Three $20.0\mathrm{mL}$ samples of nitric acid are titrated with a $0.200\mathrm{mol}/\mathrm{L}$ solution of sodium hydroxide. The results for the three trials are shown in the table below. What is the concentration of the nitric acid? (R markel
