Question 0

What is product

Answer 0

A substance that forms in a chemical reaction

Question 1

What is Reactant

Answer 1

A substance or molecule that participates in a chemical reaction

Question 2

What is chemical energy

Answer 2

The energy released when a chemical compound reacts to produce new compounds

Question 3

What is exothermic reaction

Answer 3

A chemical reaction in which heat is released to the surrounding. An example would be isooctane-oxygen reaction

Question 4

What is endothermic reaction

Answer 4

A chemical reaction that requires heat. And example would be like if you put hydrated barium hydroxide and ammonium nitride together in a flask, the reaction between them takes so much energy from the surroundings that water in the air will condense and then freeze on the surface of the flask.

Question 5

What is synthesis reaction

Answer 5

A reaction which two or more substances combine to form a new compound

Question 6

What is decomposition reactions

Answer 6

A reaction in which a single compound breaks down to form two or more simpler substances

Question 7

What is electrolysis

Answer 7

The process in which an electric current is used to produce a chemical reaction, such as the decomposition of water

Question 8

What is combustion reaction

Answer 8

The oxidation reaction of an organic compound, in which heat is released

Question 9

What is single-displacement reaction

Answer 9

A reaction in which one element or radical takes the place of another element or radical in a compound

Question 10

What is double-displacement reaction

Answer 10

A reaction in which a gas, a solid, or a molecule compound forms from the apparent exchange of atoms or ions between two compounds

Question 11

What is oxidation-reduction reaction

Answer 11

Any chemical change in which one species is oxidized and another species is reduced, also called redox reaction

Question 12

What is radicals

Answer 12

An organic group that has one or more electrons available for bonding

Question 13

What is chemical equation

Answer 13

A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products

Question 14

What is mole ratios

Answer 14

The relative number of moles of the substances required to produce a given amount of product in a chemical reaction

Question 15

What is coefficient

Answer 15

A numerical measure of a physical or chemical property that is constant for a system under specified conditions.

Question 16

What is law of conversation of matter

Answer 16

the principle that in any closed system subjected to no external forces, the mass is constant irrespective of its changes in form; the principle that matter cannot be created or destroyed.

Question 17

What is law of definite proportions

Answer 17

states that a chemical compound always contains exactly the same proportion of elements by mass.

Question 18

What is catalysts

Answer 18

A substance that changes the rate of a chemical reaction without being consumed or changed significantly

Question 19

What are enzymes

Answer 19

A type of protein that’s speeds up metabolic reactions in plants and animals without being permanently changed or destroyed

Question 20

What is substrate

Answer 20

A part, substance, or element that lies beneath and supports another part,substance, or element. The reactant in reactions catalyzed by enzymes

Question 21

What is chemical equilibrium

Answer 21

A state of balance in which the rate of a forward reaction equals the rate of the reverse reaction and the concentrations of products and reactants remain unchanged
