The reaction of sodium(s) with water(l) to form sodium hydroxide(aq) and hydrogen(g) proceeds as follows: 2Na(s) + 2H2O(1)—>2NaOH(aq) + H2(g) When 5.91 g Na(s) reacts with sufficient H2O(1), 47.4 kJ is evolved. Calculate the value of A,H for the chemical equation given. kJ/mol Submit Show Approach Show Tutor Steps
Collecting Gas over water Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H20(1)—>2NaOH(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 25 °C and a pressure of 746 mm Hg. If the wet H2 gas formed occupies a volume of 7.28 L, the number of grams of H, formed is g. The vapor pressure of water is 23.8 mm Hg at 25 °C.
