Solid sodium metal will reacts with liquid water to form sod

Solid sodium metal will reacts with liquid water to form sodium hydroxide [NaOH (aq)]
and Hydrogen gas. The standard Enthalpy of this reaction is -368.4 kJ.

How do I write the stoichiometric/balanced equation for this reaction?

How much sodium metal and water would have to be used to produce enough heat
to cause the temperature of 1 liter of water in a surrounding water jacket to increase
from 25.00C to 25.50 C? (The specific heat of water is 4.18 J/g C and a density
of 1.00 g/ml can be assumed. )

Solution Preview

First write the reaction:
2Na + 2H2O = 2NaOH + H2

The amount of heat required to heat up 1 liter of water:
Q=mcdeltaT
with m =1kg
c =4.18 ...
