Answer:

  (3.5, 17)

Step-by-step explanation:

It would be nice to see the whole graph, so we can see where the functions cross.

Without that information, we can still eliminate unreasonable choices.

A) the quadratic at y=3.5 is well above the exponential

B) the most likely choice (3.5, 17)

C) at x=-8, the quadratic is above the exponential

D) neither graph goes anywhere near y = -8

the radius of the aluminum atom is 143pm. the radius of the aluminum atom is 54pm. by what percentage did the radius change as t
Dennis_Churaev [7]

Answer:

There was 62.23% change in radius as the ion formed.

Step-by-step explanation:

Given

Radius of Aluminium (Al) atom  = 143 pm

Radius of Aluminium (Al^{3+}) atom  = 54 pm

Change is the radius =  Radius of Aluminium (Al) atom - Radius of Aluminium (Al^{3+}) atom = 143 -54 = 89

Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium (Al) atom and multiply by 100 we get

% Change is the radius = \frac{\textrm{Change is the radius}}{\textrm{Radius of Aluminium (Al) atom}} \times 100 = \frac{89}{143}\times100= 62.23\%

Hence there was 62.23% change in radius as the ion formed.
