Calculate the Heat of reaction for this equation, then determine if bonds are breaking or forming O2(g) 0.0
NO (g) 90.37
NO2 (g) 33.85
2NO(g) + O2(g) 2NO2 (g)

A-248.44 KJ, bonds forming
B 0-113.04 KJ bonds forming
C 248.44 KJ, bonds breaking
D 113.04 KJ bonds breaking​

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
