Hello and thank you for posting your question to Brainmass.

a) From the equation we see that if 3 moles of H2 fully react, then we get 21941 calories.
So if 5 moles of H2 fully react, we get:

Q=5/3 * 21941 = 36568 Cal.

b) Again if we look at the species coefficients in the equation we see that if 3 moles of H2 fully react, we get 2 moles of ...

Solution Summary

The solution provides a detailed, step-by-step walk through of the calculations one must do to find the number of calories of heat produced from a hydrogen reaction, using the bai equation, as well as determining if the reaction is endo- or exothermic.
