Bc Science 10 Chapter 6

Front 1

Catalyst

Back 1

A substance that speeds up the rate of reaction without being changed/used up.

Front 2

Catalytic Converter

Back 2

Converts poisonous gases from the vehicles exhaust into less harmful substances.

Front 3

Combustion

Back 3

The fast reaction of a compound/element with oxygen gas to form an oxide to produce heat.

Front 4

Decomposition

Back 4

Chemical reaction where a compound is broken down into 2 or more elements/simpler compounds.

Front 5

Double Replacement

Back 5

2 ionic solutions that react to produce 2 other ionic compounds. Produces precipitate.

Front 6

Neutralization (acid-base)

Back 6

Chemical reaction that happens when an acid and a base react to make a salt and water.

Front 7

Precipitate

Back 7

Insoluble solid that forms from a solution.

Front 8

Rate of Reaction

Back 8

How fast products form in a chemical reaction.

Front 9

Single Replacement

Back 9

A reactive element and a compound react to produce another element and another compound.

Front 10

Surface Area

Back 10

Measure of the amount of area an object is exposed. Effects reaction rate.

Front 11

Synthesis

Back 11

Chemical reaction where 2 elements combine to produce a single product.

Front 12

Temperature

Back 12

The average energy of molecules. More energy: higher temperature.

Front 13

Concentration

Back 13

How many molecules exist in a certain volume. How much solute is dissolved in a solution. Higher concentration: Faster reactions.

Front 14

Surface Area (chemical reactions)

Back 14

When and where atoms compounds collide. More surface area: Faster reaction.

Front 15

Enzymes

Back 15

Biological catalyst.

Front 16

Endothermic

Back 16

Energy is absorbed.

Ex. photosynthesis, melting, cooking of an egg, evaporation.

Front 17

Exothermic

Back 17

Energy is released.

Ex. water vapor condensing, rusting of iron, nuclear fission, spontaneous combustion.

Front 18

Kinetic Energy

Back 18

Energy of a particle or an object due to it's motion.

Front 19

Potential Energy.

Back 19

Stored Energy.
