'Calculate the standard enthalpy change for the oxidation of ammonia according to the equation: 4NH3(g) + 5O2(g) ----> 4NO(g) +6H2O(g) Standard enthalpies of formation are as follows: 4NH3(g)=-49kJmol-1 NO(g)=+90kJmol-1 H2O(g)=-242kJmol-1'
Can someone help me with this? And can they explain it step by step, because I'm really stuck Thankyou
