25. For the reaction: _N2 + _02 =_NO, balance the equation and determine the correct lowest mole ratio.

If 5 moles of N, reacted with 12 moles O, according to the above reaction, determine:
26. How many moles NO, are produced?
27. How many moles of N, are left in excess after the reaction (if any)?
28. How many moles of O, are left in excess after the reaction (if any)?

The enthalpy of formation of water is -285.8 kj/mol. what can be inferred from this statement?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
