A that’s the answer I’m not really 100% sure.
C. because it makes a story good, <span>those expectations get twisted around in a really good novel.</span>
Answer:
Explanation:
ΔG° = - 8.03 kJ/mol & ΔG = -45.28 kJ/mol
Thus:
Overall ΔG = (- 8.03 + 45.28) kJ/mol
ΔG = 37.25 kJ/mol
ΔG = 37250 J/mol
Temperature = 27 °C
= (27 + 273)K
= 300 K
Therefore :
ΔG = -RTInK
In K =
In K =
In K =
In K = 14. 93
K =
K =
the standard free energy of the first reaction at 27 °C =
Assuming that there is missing information in this question I’m just going to go ahead and say that it’s lower.
HNO3 (nitric acid) is a very strong acid which should be found on the lower end of the pH scale. While water, on the other hand, is neutral and found at a pH of 7.
So if you add one drop of a strong acid into a neutral solution of 100ml let’s say, one can assume that the pH of that solution is now very low and probably found between 1-3 on a pH scale.
Reminder:
-Acids are found between 1-6 on the pH scale. The lower the number the stronger the acid
-Bases are found between 8-14 on the pH scale. The higher the number the stronger the base
Density is an intensive property of an object that can be calculated by dividing the total mass by the total volume. Mathematically expressing the formula will give us,
density = mass / volume
Substituting the known values from the given,
density = 75 g / 100 mL = 0.75 g/mL
Thus, the density of the softdrinks is 0.75 g/mL.
