2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver

2 C4H8O + 11 O2 —> 8 CO2 + 8 H2O
The correct answer is iron
The radii of atoms is increasing down the group.
If we look at the group 2, we will see the the lowest element is Ra. It has largest atomic radius and it has to have largest ionic radius.
Chromosomes have genes that determine specific thing about a person (hair color, eye color, how tall or short a person is etc....).
