Answer:
Rachel needs 0.52 kg of fertilizer.
Explanation:
Since the surface is a <em>square</em> of 10 ft of size its area is A = 10 ft x 10 ft = 1.0 x 10² ft². <em>One third</em> of that space is devoted to tomatoes (<em>"space is divided equally among tomatoes, lettuce, and strawberries"</em>), that is, 1/3 x 100 ft² = 33 ft².
We calculate the kilograms of fertilizer required we need to know 2 equivalences:
1 ac = 43,560 ft²
1 lb = 0.4535 kg
Then, we can use proportions to find out the amount of fertilizer used:

Explanation:
Free energy of mixing = ΔGmix = Gf - Gi
attached below is the required derivation of the
<u>a) Molar Gibbs energy of mixing</u>
ΔGmix = Gf - Gi
hence : ΔGmix = ∩RT ( X1 In X1 + X2 In X2 + X3 In X3 + ------- )
<u>b) molar excess Gibbs energy of mixing</u>
Ni = chemical potential of gas
fi = Fugacity
N°i = Chemical potential of gas when Fugacity = 1
ΔG = RT In ( a2 / a1 )

Hello there!
In this case, according to this equilibrium temperature problem, we can set up the following equation to relate the mass, specific heat and temperature change:
Thus, we solve for the mass of cobalt as shown below:
