Lithium oxide is able to undergo both the processes of dissolution and dissociation.

Dissociation refers to the break down a chemical substance into its constituents. Ionization refers to the loss of electrons from a chemical specie while dissolving refers to the ability of a solid to form a solution.

Let us now look at each of the following species;

  • Lithium oxide undergoes dissolution and dissociation.
  • Magnesium nitride undergoes dissolution and dissociation.
  • Hydrobromic acid  undergoes dissolution and dissociation.

You are determining the density of an unknown solid. You figure out the volume by water displacement. Then you weigh the solid,
WINSTONCH [101]

Answer:

The calculated density will be larger

Explanation:

The calculated density will be <u>larger</u>. Because, the volume is taken accurately, by the water displacement method. But, when we the took the mass, the water was present on the unknown solid. So, the mass of that water was added to the original mass of the solid. Hence, the mass measured was larger than the original mass. We, know from the formula of density that density is directly proportional to the mass of the object.

Density = Mass/Volume

Hence, the larger measured mass means the larger value of density.

What is a naturally occurring, solid mass of mineral or mineral-like matter?
Firdavs [7]

Rock is a combination of two or more minerals, and it does not possess any specific chemical composition. It is present naturally in the environment. Some examples of rocks are limestone, granite, etc.,Limestone may contain minerals like calcite and aragonite. Each mineral has a specific chemical composition with a well defined crystalline structure.

Therefore, the correct option would be a. rock as rock is the naturally occurring  solid mass made up of different types of minerals.

Which of the following solutions is acidic? [H3O+] = 1.0 x 10-10 M [H3O+] &lt; 1.0 x 10-7 M [OH-] = 1.0 x 10-10 M [OH-] = 1.0 x
Burka [1]

Answer:

[OH-] = 1.0 x 10-10 M

Explanation:

The acidity of a solution can be determined directly from the concentration of the hydrogen ions and indirectly from the concentrations of the hydroxide ions.

Generally, for a neutral solution we have;

[H3O+] = [OH-] = 1.0 x 10-7 M

For an acidic solution;

[H3O+] > 1.0 x 10-7 M

[OH-] < 1.0 x 10-7 M

Comparing the options the correct option is;

[OH-] = 1.0 x 10-10 M
