C is the answer 3 + 2 +8 = 13

Answer:

C.

Explanation:

We have to keep in mind for this question that we have to take into account the <u>subscripts</u>.

Fe_3(PO_4)_2

The <u>subscript will affect only the number in the left</u>, so the first part would be:

Fe_3

In this part we will have 3 iron atoms. Then we will have:

(PO_4)_2

In the PO_4 we will have 1 atom of P and 4 atoms of O. (When we dont have any number as subscript we have to <u>assume that we have a "1</u>")

Then we have a "2" out side the the parenthesis (PO_4)_2, so we have to multiply by "2" all the <u>atoms inside the parenthesis</u>, so:

1 atom of P x 2 = 2

4 atoms of O x 2 = 8

So, in total we will have:

3 atoms of Fe + 8 atoms of O + 2 atoms of P = <u>13 atoms</u>

1.<br> How<br> many atoms of Li are there in 7.5 moles of Li?
ZanzabumX [31]

Answer: 4.52x10²⁴ atoms Li

Explanation: For 1 mole of Li it is equal to the Avogadro's Number.

Solution:

7.5 moles Li x 6.022x10²³ atoms Li/ 1 mole Li

= 4.52x10²⁴ atoms Li

Which of the following elements has the largest atomic radius?
adell [148]
<h3>Answer:</h3>

            Potassium has the largest atomic radius.

<h3>Explanation:</h3>

                        Using periodic table trends one can easily compare the atomic radii of elements. The trends in atomic radii are as follow,

Trends in Groups:

                             Moving from top to bottom along the groups the atomic radii increases because as you move from top to bottom the number of shells increases hence, the distance of valence electrons from nucleus also increases and therefore, atomic radius increases.

Trends is Periods:

                             Moving from left to right along the periods the atomic radii decreases. This is because the number of protons and electrons increases but the the valence shell remain the same hence, causing more nuclear charge and more attraction between the valence electrons and nucleus.

<h3>Result:</h3>

           Potassium, Calcium, Cobalt and Nickle all are present in same period. Potassium present at the extreme left will have greater atomic radii of 0.227 nm while Co and Ni at the middle of period will have atomic radii of 0.125 nm each. While, the atomic radius of Calcium next to K is 0.197 nm.
