3) The head of a pin is 1.5 x 103 m in diameter. If 1.136 x 107 atoms of oxygen can fit across the head of a pin, what is the atomic radius of oxygen? O A. 7.57 x 10-10 m O. 1.32 x 10-10 m O C. 1.70 x 10-4 m O D. 6.6 x 10-11 mb​

m=9

step-by-step explanation:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
