The ionization energy of an element is the amount of energy required to completely remove and electron from one more time. The ionization energy of the hydrogens is reported to be 1.31 x 10^6. Calculate the ionization energy of hydrogen in J/atom. There are 6.02x10^23atoms in a mole.

What does the cell nucleus do or, how does it function?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
