Ammonia is produced commercially by the direct reaction of the elements. the formation of 1.00 moles of gaseous nh3 by this reaction releases 46.17 kj of heat. how much energy (in kj) is released, when 28.0 kg of hydrogen gas, h2, reacts in excess nitrogen gas, n2?

of heat energy will be released

Explanation:

Balanced reaction-

According to balanced equation, moles of produces 1 mol of to release 46.17 kJ of heat.

Molar mass of = 2.016 g/mol

Number of moles = (mass)/(molar mass)

So, 28 kg of = 28000 g of

                                              = moles of

                                               = moles of

So. moles of react to release heat or of heat
