0.38 L of HNO3 is titrated to equivalence using 0.12 L of 0.2 MNaOH. What is the concentration of the HNO3? Express the concentration of HNO3 in molarity.

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
