When 0.250 mol of CH4(g) reacts with excess Cl2(g) at constant pressure according to the chemical equation shown below, 177 kJ of heat are released. Calculate the value of Delta H for this reaction, as written. 2CH4(g)+3Cl2(g)-->2CHCl3(l)+3H2(g) delta H=?

How much heat is absorbed/released when 35.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) according to the following chemical equation? 4NH3(g)+5O2(g)--->4NO(g)+6H2O(l) DeltaH=1168kj

+1420kJ?

hhmm would it be 4x that amount and not 8? im confused

i guess the teacher put a bad answer bank none of the answer are 1416 but i get what you are saying i will bring this up to him thanx

i got 601.1 are released is that right?

yeah it just says rleased/absorbed i guess that's what they want you to find out im not sure what you mean by 1168 kJ/mole or 1168 kJ/reaction?
