Sedaia [141]

Answer:

Explanation:

1 mole of Fe require 2 Moles of NiO(OH)

so for 4.25 mol of Fe and 6.70 mol of NiO(OH), Fe is the limiting reagent.

1 mole produces 1 mole of Fe(OH)2

4.25 moles will produce 4.25 moles of Fe(OH)2

The radius of a potassium atom is 231 pm. how many potassium atoms would have to be laid side by side to span a distance of 2.86

Readme [11.4K]

Answer:

$6.1905\times 10^{6}$ of potassium atoms are needed.

Explanation:

Radius of the potassium atom,r = 231 pm = $2.31\times 10^{-7} mm$

$1 pm = 10^{-9} mm$

Diameter of the potassium atom = d

$d=2r=2\times 2.31\times 10^{-7} mm=4.62\times 10^{-7} mm$

let the number of potassium atom laid side by side to span a distance of 2.86 mm be x

$x\times d=2.86 mm$

$x\times 4.62\times 10^{-7} mm=2.86 mm$

$x=\frac{2.86 mm}{4.62\times 10^{-7} mm}=6.1905\times 10^{6}$

$6.1905\times 10^{6}$ of potassium atoms would have to be laid side by side to span a distance of 2.86 mm.
