3h2(g) + n2(g)= 2nh3(g)
how many moles of nh3 can be produced from 24.0 mol of h2 and excess n2

Answer : The number of moles of produced can be 16 moles.

Solution : Given,

Moles of = 24.0 mol

The balanced chemical reaction is,

By the stoichiometry, we can say that 3 moles of hydrogen gas react with 1 mole of nitrogen gas to give 2 moles of ammonia gas as a product.

From the balanced reaction we conclude that

As, 3 moles of react to give 2 mole of

So, 24.0 moles of react to give moles of

Therefore, the number of moles of produced can be 16 moles.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
