Define water to produce hydrogen gas and sodium hydroxide

Reference no: EM13513086

Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.030 mol of Na is added to 100.00 g of water, the temperature of the resulting solution rises from 25.00°C to 37.90°C. If the specific heat of the solution is 4.18 J/(g · °C), calculate ?H for the reaction, as written.
2 Na(s) + 2 H2O(l) --> 2 NaOH(aq) + H2(g)
?H= ?
Answer is one of the following:
-90.0 kJ
-360 kJ
-5.41 kJ
-180 kJ
