The reason why Tin granules is mostly used or preferred than
just a piece of Tin because a piece of Tin is plainly metal, in which this will
be difficult in having it to be oxidized when it is exposed or in the air
rather than Tin granules.

What makes up a film badge?
<h3><u>Answer</u><u>:</u><u>-</u></h3>
a panel of photographic film exposed to the air
According to Avogadro constant 1 mole = 6.02 x 10^23 what about 9.25 x10 ^21
that is 1 mole x ( 9.25 x10 ^21) / (6.02 x10^23) = 0.0154 moles
Compound. An element is just composed of itself. A carbohydrate is a complex compound made with carbpn and lots of other elements
The number of moles of NH3 that could be made would be 0.5 moles
<h3>Stoichiometric reactions</h3>
From the balanced equation of the reaction:
N2 (g) + 3 H2(g) ----> 2NH3 (g)
The mole ratio of N2 to H2 is 1:3
Thus, for 0.50 moles of N2, 1.5 moles of H2 should be present. But 0.75 moles of H2 was allowed to react. Meaning that H2 is limiting in this case.
Mole ratio of H2 and NH3 = 3:2
Thus for 0.75 moles H2, the mole of NH3 that would be produced will be:
2 x 0.75/3 = 0.5 moles
