Polar molecules exhibit an unequal balance of charges between the individual elements of the compound. This is brought about by the large difference in their electronegativities. The H atom has the least amount of electronegativity. Then, it is a known periodic trend, that as you go downwards in a group, electronegativity decreases, and increase as you go from left to right. Thus, you can deduce that the most electronegative elements are found in the upper right corner which includes O, N and F atoms. Any bond created between Hydrogen and any of O, N and F atoms is a polar bond.
It is 14, plug it in or use inverse equations. Since they're vertical angles they are the same value. 41 = 2x+13, 28 = 2x (subtract 13), 14 = x (divide by 2).
Answer:
(a) Wavelength = 4.85 x 10^-12 m
(b) Maximum uncertainty = 5.27*10^-25 kgm/s
Explanation:
(a) Calculating the wavelength using the formula;
λ= h/p
but p = mv
Where;
m = mass of electron = 9.1 x 10-31
h = 6.625 x 10^-34
= h/mv
= 6.625 x 10^-34 / (9.1 x 10^-31 x 1.5×10^8)
= 4.85 x 10^-12 m
so, the wavelength is short enough to reveal molecular details at the atomic level.
