Answer:
the attraction water molecules have to other surfaces
Explanation:
Adhesion is defined as the attractive forces between unlike substances, e.g water moving up a capillary tube.
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another(Wikipedia).
So, what we mean by adhesion in this context, is the attraction water molecules to other surfaces.
Answer:
The answer to your question is letter B
Explanation:
a. [: C≡C :] This option is not correct because Carbon only has 4 valence electrons and carbons in this structure have 5, this structure does not exist.
b. [: N≡N :] This option is correct because because Nitrogen has 5 valence electrons and this structure shows that number of electrons.
c. No right choice. This option is incorrect because letter B is correct.
B----------- oxide is the correct answer
Answer:
The dots were not properly located and arrows are not used in Lewis structures
Explanation:
If we intend to write a Lewis structure for a compound, that lewis structure must consist of only dots. These dots actually show the valence electrons on the outermost shell of the molecule.
We do not involve arrows when writing dot electron structures for compounds. The valence electrons of magnesium ought not to be written together because they are not a lone pair, rather they are two unpaired electrons. The use of an arrow suggests a coordinate covalent bond which is not the case here.
The correct lewis structure for MgCl2 is shown in the image attached to this answer.
