Data:
P (pressure) = 2.3 atm
V (volume) = 120 L
T (temperature) = 340 K
n (number of mols) = ?
R (Gas constant) = 0.082 (atm*L/mol*K)
Formula:
Solving:
The correct answer is - mutualistic symbiotic relationship.
The mutualistic symbiotic relationship is a relationship between two or more species, in which they collaborate and have mutual benefit of their collaboration.
In this case, the pseudomyrmex ants and the acacia trees do exactly that, they collaborate for the benefit of both of them. The acacia tress provide shelter, nectar, and protein for the ants, and the ants are protecting the tree from herbivorous insects and parasitic plants. In this way, both of them benefit from each other.
Answer:
colorless
Explanation:
The ferric ion reacts with the thiocyanate, which reduces the concentration of Thiocyanate.
Answer:-3463 kJ and -3452kJ
Explanation:
ΔU is the change in internal energy of a system and its formula is;
ΔU = q + w
Where q represents heat transferred into or out of the system. Its value is positive when heat is transfer into the system and negative when heat is produced by the system.
W represents the work done on or by the system. Its value is positive when work is done on the system and negative when it is done by the system.
For the system in this question, we see that it produces heat which means heat is transferred out of the system, therefore the value of q is negative, it can also be seen that work is done by the system which means that w is also negative.
Therefore,
ΔU = -q-w
ΔU = -3452 kJ – 11kJ
= - 3463kJ
ΔH is the change in the enthalpy of a system and its formuls is;
ΔH = ΔU + Δ(PV)
By product rule Δ(PV) becomes ΔPV + PΔV
At constant pressure ΔP = 0. Therefore,
ΔH = -q-w + PΔV
w is equals to PΔV, So:
ΔH = -q
ΔH = -3452kJ
The equilibrium constant for a reaction is simply the
product of the solubility constant of the solute and the formation constant of
the product, that is:
Keq = Ksp * Kf
Keq = 1.8 × 10^−10 * 1.0 × 10^21
<span>Keq = 1.8 x 10^11</span>
