<h2>Answer:</h2>

The correct answer is option C which is,<u> "Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid".</u>

<h3>Explanation:</h3>
  • In some conditions, a water droplet remains in the droplet form on the dry surface rather than spreading on the whole surface. It covers only remains on the mall part of the surface and making a dome shape.
  • It is due to the fact that the hydrogen bond between the water molecules is much strong than the attraction between the water molecules and surface.
  • Hence the option C is correct.

denpristay [2]

The mole ratio of the reaction shows that equal volumes of hydrogen gas will be produced by the two reactions.

<h3>What is the mole ratio of a reaction?</h3>

The mole ratio of a reaction is the ratio in which the reactants and products of a given reaction occur for the reaction to proceed to completion.

The mole ratio of a reaction is also known as the stoichiometry of the reaction.

The equation of the two reactions are given below:

Mg + 2HCl \rightarrow MgCl_2 + H_2

Mg + 2CH_3COOH \rightarrow (CH_3COO)_2Mg + H_2 \\

From the equation of the reaction reaction, an equal volume of hydrogen gas will be produced by the two reactions.

Therefore, the mole ratio of the reaction shows that equal volumes of hydrogen gas will be produced by the two reactions.

Why do minerals with metallic bonds conduct electricity so well?
Roman55 [17]

Answer and Explanation:

Because metallic bonding involves delocalized electrons. It is described as a "<em>sea of electrons</em>", because the electrons are not confined around the nucleus of metal atoms, but they are delocalized: thay can be located in one nucleus and then in another neighbor atom. Thus, the electrons have more freedom to move from one part of the metal to another and electricity is well conducted.

Do equal volumes of the same gas at the same temperature and pressure contain equal numbers of molecules (number of moles)?
tresset_1 [31]

Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.

Explanation:I hope it works for you.
