Homework Help: Chemistry

Posted by Riley on Sunday, March 18, 2012 at 4:43pm.

1.00 g of sodium is added to a large excess of water under conditions of constant pressure (1.00 atm) and constant temperature (25 C ). The following reaction occurs:

2Na (s) +2H2O (l)------> 2NaOH (aq) +H2(g)
Delta Hrxn =-369 kJ/mol

Calculate the heat released after 1.00 g of Na(s) fully reacted. Atomic weight of Na is 23.0 g/mol

Could you please tell me how to do this! Thank you!
