Acids and ases first quiz

Question 1

What is empirical ?

Answer 1

Empirical refers to knowledge or information that is based on observable and measurable evidence.

Question 2

What is theoretical?

Answer 2

Based on ideas or concepts that explain something.
It’s more about thinking and understanding how things work, even if you can’t see them directly.

Question 3

What does matter break down into?

Answer 3

Pure substances and mixtures

Question 4

What do both pure substances and mixtures break down into?

Answer 4

Pure substances break down into compounds and elements.
Mixtures break down into homogenous and heterogenous mixtures.

Question 5

What is a solution empirically and theoretically?

Answer 5

Empirically, a solution is homogeneous because its properties are consistent throughout. Theoretically, it is uniform at the atomic and molecular levels.

Question 6

What is the normal prerequisite for chemical change?

Answer 6

dissolving substances

Question 7

What is a matter?

Answer 7

anything that has mass and occupies space

Question 8

What is uniform in science?

Answer 8

In science, when something is described as uniform, it means that its properties, appearance, or composition are identical throughout.

Question 9

What is a pure substance?

Answer 9

Made up of one thing only

Question 10

What is a compound?

Answer 10

substance made up of 2 or more elements

Question 11

What is an element?

Answer 11

Substance made up of only one type of atom

Question 12

What is a mixture

Answer 12

combination of 2 or more substances

Question 13

What is a homogenous mixture

Answer 13

A homogeneous mixture is one where the components are evenly distributed, so it looks the same throughout.

Question 14

What is a heterogenous mixture

Answer 14

A heterogeneous mixture has unevenly distributed components, so you can often see the different parts.

Question 15

What is the definition of “dissolving”

Answer 15

A process in which
Dissolving is the process where a substance (the solute) breaks down and mixes evenly into another substance (the solvent) to form a solution.

Question 16

What is dissociation

Answer 16

Dissociation is the process where a compound breaks apart into smaller particles, such as ions or molecules, when it dissolves in a solvent.

Question 17

WHat is ionization

Answer 17

the process by which an electrically charged neutral atom or molecule is converted to an ion, from the loss or gain of electrons

Question 18

H20 molecules gradually surrounding ions

Answer 18

Hydration

Question 19

The seperation of ions from each other

Answer 19

Dissociation

Question 20

The surrounding of solute particles by solvent

Answer 20

solvation

Question 21

How do you know a compound is electrolytic

Answer 21

If their aqueous solutions conduct electricity

Question 22

Why do molecular compounds not conduct electricity

Answer 22

becuase there isnt a presence of ionic bonds to conduct electricity

Question 23

What is the process of dissolving

Answer 23

1. bonds between the particles in the solute break(endothermic)
2. Intermolecular foces between particles in the solvent also break(endothermic)
3. The attraction between the particles of a solute and the particles of solvent result in the formation of chemical bons(exothermic)

Question 24

What is an endothermic process

Answer 24

If more energy is absorbed to break the bonds then amount of energy releases when the bonds are formed, the change is endothermic.

Question 25

What is an exothermic process

Answer 25

If more energy is released when the solute solvent bonds form than is required to dissolve the solvent then the overall process is exothermic

Question 26

Solubility

Answer 26

Ability to dissolve

Question 27

What is a saturated

Answer 27

Saturated is a state in which a solution contains the maximum amount of solute that can dissolve. After this point, any additional solute will not dissolve and will remain as a solid in the solution.

Question 28

What is unsaturated

Answer 28

Unsaturated refers to a solution that has less solute than the maximum amount that can be dissolved. In this state, more solute can still dissolve without any of it remaining undissolved.

Question 29

In what conditions are gases highly soluble at normally

Answer 29

at high pressures and low temperatures

Question 30

In what condtions are solids highly soluble at normally

Answer 30

at high temperatures

Question 31

In what conditions are liquids highly soluble at normally

Answer 31

at high temperature

Question 32

solubility equilibrium

Answer 32

established by adding a solute to a solvent
