0.00167265 mm
Explanation:
Given the spacing between the molecules in the crystal is 15.93 nm.
1 nm = 
m
so 15.93 nm = 15.93 * = 1.593 * 
m
Spacing between 2 molecules is 1.593 * m
So total width of 105 molecules crystal is 1.593 * *105 = 167.265 * m
We know that
1 m = 1000 = 
mm
So total width of 105 molecules crystal in millimeters is 167.265 * *
= 167.265 * 
= 1.67265 * 
mm = 0.00167265 mm

Convection which allows heat to be transferred between the air molecule via convection currents .
Sn + 2Cl2 ------> SnCl4
from reaction 2 mol 1 mol
from the problem 2.85 mol x mol
x=2.85*1/2≈1.43 mol SnCl4
Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20
