Answer:
Square planar.
Explanation:
Hello,
In this case, it can be demonstrated that the central atom Xenon in XeF₄ has a sp³d² hybridization which means that its geometry is likely to be octahedral. Nevertheless Applying by applying the valence shell electron pair repulsion (VSEPR) model to in order to minimize the repulsion among lone pairs, bond pairs and lone pair-bond pairs, we we realize repulsion is actually minimized when lone pairs are anti to one another and the fluorine atoms are in equatorial position, for that reason, the corrected and properly exhibited geometry or molecular arrangement of the compound turns out square planar. You can verify it on the attached picture.
Regards.
Answer:
is the molar concentration of Cu(II) ions in the unknown solution.
Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution
C = concentration of solution
l = length of the cell =
= molar absorptivity of solution
A Beer's law plot is between absorbance and concentration.
We have:
A = 0.55
The slope of the Beer's law plot = m = 310 L/mol
So, the concentration of the solution is:
is the molar concentration of Cu(II) ions in the unknown solution.
