A molecule with the formula ch3ch(nh2)cooh probably exhibit which of the folloiwng characteristics

1 answer:

3 0

Considering the answers;
1)Molecules with this formula would likely be hydrophobic.
2)Polymers of this molecule can serve as storage or structural components. 
3)The side chains of this molecule would determine its function. 
4)This type of molecule serves as a vehicle for transmission of genetic material
The correct answer is; 2) Polymers of this molecule can serve as storage or structural components.
The molecule shown in the question is an amino acid; alanine to be specific.
The molecule is not hydrophobic; The side chain does determine its function, but only in comparison with other amino acids that do not share this formula. Amino acids are not vehicles for genetic material; that's nucleic acids.

Consider the following reaction at 298 K:

faltersainse [42]

Answer :

$\Delta S_{sys}$ = -1622.8 J/K

$\Delta S_{surr}$ = -94.6 J/K

$\Delta S_{univ}$ = 0 J/K

Explanation : Given,

$\Delta H$ = -483.6 kJ

The given chemical reaction is:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(g)$

First we have to calculate the value of $\Delta S_{sys}$ .

$\Delta S_{sys}=\frac{\Delta H}{T}$

$\Delta S_{sys}=\frac{-483.6kJ}{298K}$

$\Delta S_{sys}=-1.6228kJ/K=-1622.8J/K$

Entropy of system = -1622.8 J/K

As we know that:

Entropy of system = -Entropy of surrounding = 1622.8 J/K

and,

Entropy of universe = Entropy of system + Entropy of surrounding

Entropy of universe = -1622.8 J/K + (1622.8 J/K)

Entropy of universe = 0

The highest energy occupied molecular orbital in the f-f bond of the f2 molecule is _____

Morgarella [4.7K]

The basis of finding the answer to this problem is to know the electronic configuration of Fluorine. That would be: [He] 2s² 2p⁵. The valence electrons, which are the outermost electrons of the atom, are the ones that participate in bonding. Since the highest orbital for F is 2p, that means the highest energy occupied would be 2.
