Dec 23, 2008 · Ok, first we need to figure out the lewis structure of XeF2. To do that we first need to count up the total number of valence electrons we will need in the structure. Xe contributes 8 and each fluorine contributes 7 for a total of 22 valence electrons. So now draw Xe at the center with one bond to each fluorine.

May 30, 2006 · So, what you have is an Xe atom with three lone pairs oriented in a planar triangle shape (I visualize them horizontally) with one Fl atom below the triangle and another above. The result is a linear shape for the XeFl2 molecule, but if you include the electrons in the geometry, its technically trigonal bipyramidal.

Apr 18, 2015 · The first thing you need to do when trying to figure out how the Lewis structure of a molecule looks like is to determine how many valence electrons that Lewis structure must account for.

Jul 22, 2007 · It just dawned on me that school is starts in less than a month:scared:. I am registered for a linear algebra course. For those who have taken the class, is it purely algebra, or does it have some calculus? heavens knows I can't take anymore derivatives in my life or I will+pissed+. Thanks

Feb 19, 2015 · Given two sets A and B (they could be sets of numbers, but also what you want...), a relation is a certain number of arrows that joints some elements of A with some elements of B. A function is a particular relation that joints every element of A with one and only one element of B.

Apr 29, 2011 · The depiction I'm using is confusing, but that's how it was taught to me. Something that's probably more intuitive instead, is rather than focusing on where the -CH2OH group is appearing within the molecule, instead just look at the anomer itself:

Mar 8, 2016 · I increased my score from 478 to 495 in 3 weeks. I do content review/studying about 5-6 hours per day. I have been using all Kaplan materials and TPR practice passages.

Nov 15, 2009 · Hi everyone, I just got invited to interview for two of the MFT programs that I applied for. One interview includes a one-on-one interview with a faculty member AND a group interview. The other school requires a looong 3-4 hour group interview. First of all, I've never done a group interview...

Nov 29, 2012 · -Particle deflectors! they love this one. For example, finding the radius of curvature a particle will experience in a magnetic field by setting Fmag=Fcentripetal. Also, setting the force applied by an electric field equal to force of magnetic field and solving for the velocity required for linear motion.-Resonance and beat frequencies.

Aug 8, 2017 · -7ltxlt4 For (x+7)/(x-4) to be less than 0, the top part must be less than 0, or negative. An x value of -7 will cancel the top part, but only give us 0, anything less than -7 will give a negative fraction, and therefore less than 0.
