Post by: Whelan on May 6, 2015
Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.015 mol of Na is added to 100.00 g of water, the temperature of the resulting solution rises from 25.00°C to 31.45°C. If the specific heat of the solution is 4.18 J/(g ∙ °C), calculate ΔH for the reaction, as written.

   2 Na(s) + 2 H2O(l) → 2 NaOH(aq) + H2(g)   ΔH = ?     

A) -5.41 kJ
B) -90.0 kJ
C) -180 kJ
D) -360 kJ
