Sonia observed that the two balloons repelled each other. This is because both balloons acquired the same charge when she rubbed them with the piece of wool, and like charges repel each other.
Answer:
See explanation
Explanation:
We know that
%ic of the interatomic bond = [1 - e^-(XA - XB)^2/4] * 100%
Now;
XA = electronegativity of Ti = 1.61
XB = electronegativity of Al = 1.54
Substituting values;
%ic of the interatomic bond = [1 - e^-(1.61 - 1.54)^2/4] * 100%
%ic of the interatomic bond = 0.12%
Given the low %ic of the interatomic bond, the bond is metallic.
Answer:
Oxygen exists as a diatomic molecule in nature when it is not combined with any other element. It forms O2 molecule because it is stable when it is uncombined. ... By achieving octet configuration, the diatomic elements become more stable compared to the single atom. Therefore, oxygen and hydrogen are diatomic.

First you should find no of mole.
a mole is a measurement of the number of number of grams in which there are 6.02 x 10^23 atoms/molecules of a substance.
1.468 moles of NH3 in 25 grams.
(25/17.0306) 1.468 x (6.02 x 10^23) = 8.837 x 10^23 molecules.
hope this help
