Chemistry Student Please Help
i am doing a resit paper, and i got my paper back, i don't have the mark scheme, so i was wondering if any chemistry could tell me if i have the correct answer.
If i have the wrong answer, where have i gone wrong,
ntiric acid can be made by reacting water, nitorgen dioxide and oxygen according to the following equation:
H2O + 2NO2 + 1/2O2 ----> 2HNO3
with standard enthalpy vaule ^H (delta H) -128kjmol-1
with delta H of formation/kjmol-1 values for
H20 (-286)
NO2 (+34)
02(0)
using this data calulate a value for the standard enthalpy of formation of nitric acid.
