Answer:
for the reaction is -198.762 J/K
Explanation:
Standard change in entropy for the system () is given by-
![\Delta S^{0}=[2moles\times S^{0}(NH_{3})_{g}]-[1mole\times S^{0}(N_{2})_{g}]-[3\times S^{0}(H_{2})_{g}]](https://tex.z-dn.net/?f=%5CDelta%20S%5E%7B0%7D%3D%5B2moles%5Ctimes%20S%5E%7B0%7D%28NH_%7B3%7D%29_%7Bg%7D%5D-%5B1mole%5Ctimes%20S%5E%7B0%7D%28N_%7B2%7D%29_%7Bg%7D%5D-%5B3%5Ctimes%20S%5E%7B0%7D%28H_%7B2%7D%29_%7Bg%7D%5D)
where 
represents standard entropy.
Here 
, 
and 
So, ![\Delta S^{0}=[2\times 192.45]-[1\times 191.61]-[3\times 130.684]J/K=-198.762J/K](https://tex.z-dn.net/?f=%5CDelta%20S%5E%7B0%7D%3D%5B2%5Ctimes%20192.45%5D-%5B1%5Ctimes%20191.61%5D-%5B3%5Ctimes%20130.684%5DJ%2FK%3D-198.762J%2FK)
Answer:
i also had this question.
Explanation:
I think the correct answer would be direct additives. Not proper handling of cleaning agents especially in areas where food are prepared or served would most likely add chemicals to the food which is harmful to the consumer. Hope this helps.
No.!!
As it has full filled valence electrons, they can't form bonds, due to lack of vacant electrons.
Hope this helps!
Answer:
The correct answer is - 1, 2, and 4 statements.
Explanation:
Beta and gamma turns are common plots or turns in proteins and contain intra-turn hydrogen bonds. This hydrogen bond is present between CO of residue i and NH of residue i+3 that holds the confirmation in beta turns.
Beta turns, assist the protein to get their globularity, as the aim of beta turns is to reverse the direction of the polypeptide. The two main of beta turns are type-I and type-Il. and their minor images are type-I and type-Il.
Thus, the correct answer is - 1, 2, and 4 statements.
