Question 0

Product

Answer 0

The substance that is formed from a chemical reaction

Question 1

Reactants

Answer 1

Substance that undergoes chemical reaction

Question 2

Chemical energy

Answer 2

Energy that is let out when a chemical compound reacts

Question 3

Exothermic Reaction

Answer 3

Reaction where heat is let out

Example- isooctane-oxygen reaction

Question 4

Endothermic reaction

Answer 4

Reaction that needs heat

Example- putting hydrated barium hydroxide and ammonium nitrate together

Question 5

Synthesis Reaction

Answer 5

Reaction where at least two substances come together and make a new compound

Question 6

Decomposition reaction

Answer 6

When a compound is broken apart to at least two different substances

Question 7

Electrolysis

Answer 7

When electricity is used to make a chemical reaction

Question 8

Combustion reaction

Answer 8

When an organic compound undergoes and oxidation reaction and heat is released

Question 9

Single displacement reaction

Answer 9

Reaction where one element takes the spot of another element in a compound

Question 10

Double displacement reaction

Answer 10

Reaction where a gas solid precipitate or molecular compound are made from exchange of atoms between two compounds

Question 11

Oxidation reduction reaction

Answer 11

A chemical change where one substance is oxidized or loses electrons and one substance is reduced or gains electrons

Question 12

Radical

Answer 12

Element that has electrons available for bonding

Question 13

Chemical equation

Answer 13

A chemical reaction in word format that shows how the reactants and products are related

Question 14

Mole ratio

Answer 14

How many moles of a substance are needed to form a certain amount of product in a Chemical reaction

Question 15

Oxidized

Answer 15

Substances that give up electrons.

Question 16

Reduced

Answer 16

Substances that accept electrons.

Question 17

Coefficient

Answer 17

Numbers in front of chemical formulas which tell how many of that chemical their is.

Question 18

Law of Conservation of Mass

Answer 18

Mass cannot be created or destroyed only transferred or transformed.

Question 19

Law of Definite Proportions

Answer 19

A compound always has the same proportion of the same elements no matter how the compound is made or how much of the compound there is.

Question 20

Catalyst

Answer 20

A substance that changes the how fast a chemical reaction occurs without changing dramatically.

Question 21

Enzyme

Answer 21

A protein that makes the metabolic changes in plants or animals go faster without any permanent changes.

Question 22

Substrate

Answer 22

A substance that lies beneath another substance and supports it.

Question 23

Chemical equilibrium

Answer 23

When the rate of forward reaction is the same as the rate of reverse reaction and the products and reactants stay the same.
