Answer:
P(Ar) = 358.8 mmHg
Explanation:
Given data:
Total pressure of gas = 1380 mmHg
Moles of CO₂ = 1.27 mol
Moles of CO = 3.04 mol
Moles of Ar = 1.50 mol
Partial pressure of Ar = ?
Solution:
Formula:
P(Ar) = [n₁/nt] Pt .........(1)
n₁ = moles of Ar
nt = total number of moles
Pt = total pressure
Now we will calculate the total number of moles.
nt = 1.27 mol +3.04 mol +1.50 mol
nt = 5.81 mol
Now we put the values in formula (1)
P(Ar) = [n₁/nt] Pt
P(Ar) = [1.50/5.81] 1380 mmHg
P(Ar) = 0.26 ×1380 mmHg
P(Ar) = 358.8 mmHg
I’m pretty sure it’s true
Because phospholipids have a polar end (phosphorus) and a non polar end (lipid). Similar things mix together so the phospho end likes water and the lipid end doesnt and it tucks inside the membrane

ITS IN THE QUESTION HOLLY MOTHER OF GOD
Answer:
Central-metal oxidation state: +2
Coordination number: 6
Overall charge: -2
Explanation:
In the ion complex:
Na₂[Cr(NH₃)₂(NCS)₄]
The central-metal is Cr, the ligands are NH₃ and NCS.
The NH₃ is a neutral ligand, while NCS is an anionic ligand with -1 in charge.
The overall charge of the complex is:
2Na⁺ + [Cr(NH₃)₂(NCS)₄]⁻² → <em>-2</em>
As NCS gives -1 in charge and there are four NCS, The Cr must be in <em>+2</em> of oxidation state to give an overall charge of -2.
As Cr is bonded to 2 NH₃ and 4 NCS, the coordination number is 2+4 = <em>6</em>
