Answer:

C Hydrogen bonding is the main force that attracts water molecules to

one another.

Explanation:

Hydrogen bonding affects water molecules because, it is the main force which holds and attracts water molecules to one another.

Hydrogen bonding is an intermolecular force.
Intermolecular forces holds molecules together. Examples are van der waals forces, hydrogen bonding.
In a hydrogen bonding, hydrogen of one molecule electrostatically combines with a more electronegative specie usually nitrogen, flourine and oxygen on another atom.
This attraction results in hydrogen bonding between two or more molecules.
The unique and anomalous behavior of water is as a result of these hydrogen bonds between its molecules.

What effect does heating a solid to a hightemperature have have on its crystal lattice ??

kotegsom [21]

Arrangement of atoms or group of atoms in a three dimensional ordered pattern in a crystal is said to be a crystalline lattice. They are arranged in a specific pattern with high symmetry. The heating of the crystal at high temperature will result in the increase of vibrational kinetic energy of the atoms in the crystal and this will result in the breaking of lattice apart and due to the breaking of lattice apart the ions will flow freely.

Thus, the heating of a solid at high temperature will lead to the lattice breaks apart and ions will flow freely.

Copper chloride bihydrate. What might this name tell you about the atoms in this compound

lozanna [386]

Answer : The atoms in this compound are Copper(Cu), Chlorine(Cl), Hydrogen(H), Oxygen(O).

Explanation :

The given compound is copper chloride bi-hydrate which is also called as copper (II) chloride dihydrate as it contains two water of crystallisation.

The formula of copper chloride bi-hydrate is $CuCl_2.2H_2O$ .

Therefore, there are 4 atoms in this compound and they are Copper(Cu), Chlorine(Cl), Hydrogen(H) and Oxygen(O).

A solution is made containing 4.6 g of sodium chloride per 250g of water.

lozanna [386]

Answer:

$\large \boxed{1.81 \, \%}$

Explanation:

$\text{Mass percent} = \dfrac{\text{mass of solute} }{\text{mass of solution}} \times 100 \, \%$

Data:

Mass of NaCl = 4.6 g

Mass of water = 250 g

Calculations:

Mass of solution = mass of NaCl + mass of water = 4.6 g + 250 g = 254.6 g.

$\text{\% m/m} = \dfrac{\text{4.6 g} }{\text{254.6 g}} \times 100 \, \% = \mathbf{1.81 \, \%}\\\\\text{The percent by mass of NaCl is $\large \boxed{\mathbf{1.81 \, \%}}$}$
