Answer:
ΔG = -8.812 kJ/mol
Explanation:
To obtain the free energy of a reaction you can use the expression:
ΔG = ΔG° + RT ln Q
<em>Where: </em>
<em>ΔG° is Standard Gibbs Free energy: -16.7kJ/mol = -16700J/mol</em>
<em>R is gas constant: 8.314472 J/molK</em>
<em>T is absolute temperature (37°C + 273.15 = 310.15K)</em>
<em>And Q is reaction quotient: 21.3</em>
<em />
Replacing in the formula:
ΔG = ΔG° + RT ln Q
ΔG = -16700J/mol + 8.314472J/molK*310.15K ln 21.3
ΔG = -8812.4J/mol
<h3>ΔG = -8.812 kJ/mol</h3>

Answer and Explanation:
The bond that holds together the two amino acids is a peptide bond, or a covalent chemical bond between two compounds (in this case, two amino acids). It occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule.
The amount is always constant. The answer is letter A. The carbon atom is recycle in the biosphere. It may take different forms but it is still the same carbon atom. Carbon in fuel may turn into carbon dioxide or carbon monoxide after it it burned. The CO2 may then be used up by the plants as fuel to make another form of carbon based compounds such as sugar (glucose). For more information, I suggest looking up the carbon cycle.
1) Astronomers use different measurement systems to discuss distance in the universe C) because they allow the numbers to be more manageable.
The numbers are so huge that astronomers need different units to express them.
2) The measurement system with the largest value is C) the Parsec
.
1 Parsec = 3.26 ly = 2.06 × 10⁵ AU
The volume of ideal gas that would occupy at 1.50 atm and 216 c is
2016.49 ml
<u><em>calculation</em></u>
- volume is calculated using a combined gas equation
that is P1V1/T1= P2V2/T2
P1( pressure 1) = 7.20 atm
V1 ( volume 1) = 250 ml
T1 ( temperature 1) = 18 + 273=291 K
P2 ( pressure 2) = 1.50 atm
T2 ( temperature 2)= 216+273=489 K
V2 ( volume 2) =?
- by making V2 the subject of the formula
V2=[(T2 xP1 x V1)/(T1 xP2)]
V2=[ (489 K x 7.20 atm x 250 ml) / ( 291 k x 1.50 atm)] = 2016.49 Ml
