<span>Co3+ is Cobalt with three electrons removed (It's positive by 3). So, the abbreviated notation for Cobalt, minus three electrons (Coming from 4s and 3d) is:
[Ar]4s1, 3d5</span>

Answer:
Volume of ammonia produced = 398.7 dm³
Explanation:
Given data:
Volume of N₂ = 200 dm³
Pressure and temperature = standard
Volume of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Number of moles of N₂:
PV = nRT
1 atm× 200 L = n× 0.0821 atm.L/mol.K × 273 K
n = 200 atm.L /22.41 atm.L/mol
n = 8.9 mol
Now we will compare the moles of ammonia and nitrogen.
N₂ : NH₃
1 : 2
8.9 : 2/1×8.9 = 17.8 mol
Volume of ammonia:
1 mole of any gas occupy 22.4 dm³ volume
17.8 mol ×22.4 dm³/1 mol = 398.7 dm³
From what i understood from the question,the answer is organ
Answer:1.01
Explanation:∆G(system)= ∆G(product) - ∆G(reactant)
Therefore, we have: -32 - 209.2 = -242.09 kj/mol.
Also, ∆G(system)= -RT ln kp ----{*}
R= 8.314, T= 298, kp =? , ∆G(system)= -242.09 kj/mol.
We can now substitute into equation {*}.
I.e, -242.09kj/mol= -8.314×298 ln kp
-242.09= -24477.572 ln kp
In kp= - 242.09÷ -24477.572
ln kp= 0.00989
kp= 1.0099.
