What two theories can be used to predict molecular geometry?
KIM [24]
Valence shell electron pair repulsion (VSEPR<span>) </span>theory<span> is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the Gillespie-Nyholm </span>theory<span> after its two main developers.

</span>The London theory has much similarity to the quantum mechanical theory of light dispersion<span>, which is why London coined the phrase "dispersion effect." In physics, the term "dispersion" describes the variation of a quantity with frequency, which is the fluctuation of the electrons in the case of the London dispersion.</span>

64 divided by 0.4 and explain how you did it please i don't wanna be stuck on this all night
Brrunno [24]
Okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.

so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.

so if you have
64 4
---- / ----
1 10

you would switch the 2nd one so the 10 would be on top.

so that would give you 64*10 over 1*4

which equals 640/4

& when you simplify that you get 160

so that's your answer(:

Hi guys I need help..... <br> How do you move on??
erma4kov [3.2K]

Answer:

There is no specific set way to move on.

Step-by-step explanation:

In most cases, I would say: time. With time wounds will fade; but scars will always be left behind. Do stuff that distracts you, like hobbies and devote yourself to them. Soon enough you'll forget what even happened to you.
