Question 1

What is a reactant?

Answer 1

Substance/molecule that is involved in a chemical reaction

Question 2

What is chemical energy?

Answer 2

Energy that is released in a chemical reaction that reacts, forming a new compound

Question 3

What is an exothermic and reaction+example

Answer 3

Heat being released as a result of a chemical reaction; what boiling producing heat to the air.

Question 4

What is an endothermic reaction+example

Answer 4

Heat required by a chemical reaction; freezing ice

Question 5

What is a synthesis reaction?

Answer 5

Two+ substances combing to form a compound as a result of the reaction

Question 6

What is decomposition reaction?

Answer 6

Single Compound that breaks down to form 2+ similar substances because of the reaction

Question 7

What is electrolysis

Answer 7

Electric current producing a chemical reaction

Question 8

What is combustion reaction?

Answer 8

Oxidation reaction of a organic compound which causes heat to be released

Question 9

What is single-displacement reaction?

Answer 9

Reaction causing one element to take the place of another element

Question 10

What is double-displacement reaction?

Answer 10

A gas, solid precipitate or molecular compound form due to the exchange of atoms/ions between 2 compounds

Question 11

What is oxidation- reduction reaction?

Answer 11

Chemical change where one species loses electrons (oxidized) and the other species gains electrons (reduced)

Question 12

What is radical?

Answer 12

Organic group that has 1+ electrons that can be bonded

Question 13

What is a chemical equation?

Answer 13

Showing the relationship between reactants and products shown by symbols representing the chemical reaction

Question 14

What is a mole ratio?

Answer 14

Number of moles of the substance needed to make a given amount of product in a chemical reaction

Question 15

What is a catalyst?

Answer 15

Substance that changes the rate of chemical reaction without being consumed or changed significantly

Question 16

What is an enzyme?

Answer 16

Protein that speeds up metabolic reaction in plants and animals but not permanently

Question 17

What is a substrate?

Answer 17

Part, substance or element that lies under and supports another part, substance or element.

Question 18

What is chemical equilibrium?

Answer 18

Balance where the rate of forward reaction = rate of reverse reaction and concentration of products and reactants remain the same

Question 19

What does reduced mean?

Answer 19

Substances that accept electrons

Question 20

What does oxidized mean?

Answer 20

Substances that give up electrons

Question 21

What is a coefficient?

Answer 21

Number placed in front of the chemical equation to balance the chemical equation

Question 22

What is the Law of Conservation of Mass?

Answer 22

Mass cannot be created or destroyed

Question 23

What is the Law of Definite Proportion?

Answer 23

A chemical compound always contains the same proportion of elements by mass
