Answer:
i answered the other one in few
Explanation:
Well, according to the law of conservation of mass, the total mass of the reacting atoms must equal the total mass of the final rearranged products produced through the reaction. Assuming that both products are the only products produced, it would constitute the total matter produced, and since each product has a mass of 25 grams each. The total would be 50 grams. Thus the total mass of the reactants also would need to be 50 grams, as no matter is lost in a chemical reaction.
Nylon 6,6 is a common example of a polyamide.
<em>Polyamides</em> are polymers that contain <em>repeating amide (-CO-NH-) linkages</em>.
The structure of Nylon 6,6 is
[-NH-(CH_2)_6-<u>NH-CO</u>-(CH_2)_4-CO-]_<em>n</em>
where <em>n</em> is a large number.
The numbers in the name showow that there are six carbon atoms on either side of an amide linkage.
N₂ : limiting reactant
H₂ : excess reactant

Given
mass of N₂ = 100 g
mass of H₂ = 100 g
Required
Limiting reactant
Excess reactant
Solution
Reaction
<em>N₂+3H₂⇒2NH₃</em>
mol N₂(MW=28 g/mol) :

mol H₂(MW= 2 g/mol) :

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactans become a limiting reactants
From the equation, mol ratio N₂ : H₂ = 1 : 3, so :

N₂ becomes a limiting reactant (smaller ratio) and H₂ is the excess reactant
