Answer is: 0,1053 <span>moles of hydrogen are produced.
</span><span>
Chemical reaction: </span>2NH₃ → 3H₂ + N₂.<span>
n(N</span>₂) =
0,0351 mol..<span>
From chemical reaction: n(N</span>₂) : n(H₂) = 1 : 3.
n(H₂) = 3 · 0,0351 mol.
n(H₂) = 0,1053 mol.
n - amount of substance.
They provide a place for marine life to flourish, that would otherwise most-likely go extinct because of the constant decrease of natural reefs in our oceans.
An example of a heterogeneous catalyst is a catalytic converter. A catalytic converter is an emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (oxydation or reduction).
