What two theories can be used to predict molecular geometry?

1 answer:

5 0

Valence shell electron pair repulsion (VSEPR) theory 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 theory after its two main developers.

The London theory has much similarity to the quantum mechanical theory of light dispersion, 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.

9× 3 1/2= Which choice is the most reasonable answer?

icang [17]

Answer:

31.5 or 63/2

Step-by-step explanation:

to do this, first you need to transform the mixed number (3 1/2) into an improper fraction, to get 7/2.

then you just multiply 9 by 7/2

9/1 (7/2)

63/2 = 31.5

both of the answers in bold are correct

Solve for x and y 4x-3y=14,6x +y=-10

Anna [14]

Answer:

y= -8/11 x=-63/11

Step-by-step explanation:

Rewrite equation

Step: Solve6x+y=−10for y

Step: Substitute−6x−10 for y in 4x−3y=14

Step: Substitute −8 /11 for x in y=−6x−10

y= −62 /11 --- (Simplify both sides of the equation)

___________________________________________

y= -8/11

x=-63/11
