Calculate the number of moles in 136g of ammonia
amm1812

Answer:

8moles

Explanation:

We are given the mass of ammonia to be 136g

  Ammonia = NH₃  

Let us find the number of moles in ammonia;

 Number of moles  = \frac{mass}{molar mass}  

  Molar mass of ammonia = 14 + 3(1) = 17g/mol

so;

   Number of moles  = \frac{136}{17}   = 8moles

which has a higher entropy for the reaction: 2nh3(g)→n2(g) 3h2(g) which has a higher entropy for the reaction: reactants product
krok68 [10]

The one that has a higher entropy for the reaction is products.

<h3>What is entropy?</h3>

Entropy is a measureable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty. It is the measurement of the amount of thermal energy per unit of temperature in a system that cannot be used for productive work. It is a measure of a system's molecular disorder or unpredictability since work is produced by organized molecular motion.

It should bm be noted that the entropy of gas is more than entropy of aqueous which is more than the entropy of liquid and the entropy of solid.

On the product side there are more gas than the reactant side. Therefore, product has more entropy.
