C. The number of moles of solute remains unchanged.

Answer from: joyandfaye

(Since my answer contradicts the other one here, let me reassure you that my answer is correct by stating that I’m currently doing my Ph. D. in Chemistry.)

A diluted solution is one in which the concentration of a dissolved solid (called the solute) is decreases via the addition of excess solvent. This means that A is a true statement.

Since molarity is a measurement of concentration, based on the conclusion for A, B is also a true statement.

For a given solution, excess solvent is added but the amount of solute present isn’t affected. This means that the number of solute moles is constant and the number of solvent moles is not; C is a true statement, whereas D is false.

Hope this helps!

Answer from: Quest

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in $h_{2}s$ , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between $h_{2}s$ molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent $h_{2}s$ molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

answer: $2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

the reaction is type of combination reaction.

explanation:

$? c_5h_5+? fe\rightarrow ? fe(c_5h_5)_2$

on the product side, there are 2 molecules of $c_5h_5$ bonded to fe which means one atom of fe are combined two molecules of $c_5h_5$ . so, balanced chemical equation becomes :

$2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

$a+b\rightarrow ab$
