something done, felt, or thought in response to a situation or event.

Question 3

Observation

Answer 3

the action or process of closely observing or monitoring something or someone.

Question 4

Solubility

Answer 4

Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent.

Question 5

Combination

Answer 5

a joining or merging of different parts or qualities in which the component elements are individually distinct.

Question 6

Exchange

Answer 6

an act of giving one thing and receiving another (especially of the same kind) in return.

Question 7

Thermal Decompisition

Answer 7

Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat.

Question 8

Displacement

Answer 8

the action of moving something from its place or position.

Question 9

Reactant

Answer 9

a substance that takes part in and undergoes change during a reaction.

Question 10

Product

Answer 10

a thing or person that is the result of an action or process.

Question 11

Spectator Ions

Answer 11

A spectator ion is an ion that exists as a reactant and a product in a chemical equation.

Question 12

Precipitate

Answer 12

cause (a substance) to be deposited in solid form from a solution.

Question 13

Element

Answer 13

an essential or characteristic part of something abstract.

Question 14

Ion

Answer 14

atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.

Question 15

Atom

Answer 15

the smallest particle of a chemical element that can exist.

Question 16

Proton

Answer 16

a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron.

Question 17

Electron

Answer 17

a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

Question 18

Neutron

Answer 18

a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

Question 19

Solution

Answer 19

a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).

Question 20

Aqueous

Answer 20

like water , watery

Question 21

Activity Series

Answer 21

The activity series is a useful guide for predicting the products of metal displacement reactions.

Question 22

Cation

Answer 22

a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis.

Question 23

Anion

Answer 23

a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.

Question 24

Ionic Compound

Answer 24

Ionic Compounds Are Balanced. Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-.

Question 25

Molecule

Answer 25

a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Question 26

Compound

Answer 26

a thing that is composed of two or more separate elements; a mixture.
