there are 3.78 liters of methane gas collected over water at 15.0 C and 691 mmHg. What is the new pressure of the dry gas after the temperature changes to 47.0 C and the volume increases to 5.94 liters

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?

Word equation for k(s) +h2o(l) yield koh (aq) + h2
