Answer:
When nitrogen is returned to the soil when dead plants decompose, the interaction is between which two spheres?
Geosphere and biosphe
Explanation:
Answer:
"The number of air molecules above a surface determines air pressure. As the number of molecules increases, they exert more pressure on a surface, and the total atmospheric pressure increases. By contrast, if the number of molecules decreases, so too does the air pressure."
Mass percentage is defined as the ratio of mass of the element to the total mass of the compound.
The formula of mass percentage is given by:
Mass percentage = (1)
mass of nitrogen = 56.00 grams
Let x be the total mass of the compound.
Put the given values in formula (1):
x=
x= 151.92 g
total mass of the compound = 151.92 g
To calculate the mass of oxygen in grams, subtract the mass of nitrogen from the total mass of the compound.
Mass of oxygen = 151.92 g - 56 .00 g = 95.92 g
Thus, mass of oxygen in grams = 95.92 grams.
Answer:
ΔG° of reaction = -47.3 x J/mol
Explanation:
As we can see, we have been a particular reaction and Energy values as well.
ΔG° of reaction = -30.5 kJ/mol
Temperature = 37°C.
And we have to calculat the ΔG° of reaction in the biological cell which contains ATP, ADP and HPO4-2:
The first step is to calculate the equilibrium constant for the reaction:
Equilibrium Constant K =
And we have values given for these quantities in the biological cell:
[HP04-2] = 2.1 x M
[ATP] = 1.2 x M
[ADP] = 8.4 x M
Let's plug in these values in the above equation for equilibrium constant:
K =
K = 1.47 x M
Now, we have to calculate the ΔG° of reaction for the biological cell:
But first we have to convert the temperature in Kelvin scale.
Temp = 37°C
Temp = 37 + 273
Temp = 310 K
ΔG° of reaction = (-30.5 ) + (8.314)x (310K)xln(0.00147)
Where 8.314 = value of Gas Constant
ΔG° of reaction = (-30.5 x ) + (-16810.68)
ΔG° of reaction = -47.3 x J/mol
