Write the equation in exponetial function

1 answer:

3 0

First let's solve for the rate, "b", by setting up a ratio with the two points given:

16.875/7.5=(ar^3)/(ar)

2.25=r^2

r=1.5

Now we need to solve for the initial value a using either point given...

7.5=a(1.5)^1

7.5=1.5a

a=5

So now we have solved for both variables and have a complete equation:

y=5(1.5)^x

How many outer atoms and lone pairs are present in a molecule with a square pyramidal shape?

arlik [135]

Answer:

5 Outer and 1 lone pair

Step-by-step explanation:

A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.

Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is $sp^{3} d^2$ .

One of the most common example is Xenon tetraflouride. $XeF_4$ . Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
