Chemical Reactions

Question 1

-processes by which chemicals interact with one another to form a new compound (when chemical bonds between atoms are formed and broken)

Answer 1

Chemical Reactions

Question 2

Types of Chemical Reactions:

-substance reacts with oxygen gas, releasing a large amount of energy in the form of light and heat

Example:
hydrocarbons > results in the formation of carbon dioxide and water

Answer 2

Combustion Reactions

Question 3

Types of Chemical Reactions:
-combination reactions

-reactions where two or more simple substances (generally elements) combine to form new compounds

Answer 3

Synthesis Reactions

Question 4

Types of Chemical Reactions:

-a compound is broken down into simpler compounds or even its starting elements

-can be regarded as the opposite of synthesis reactions

• popossible through the application of either heat, energy, a catalyst, or a combination of these.

Answer 4

Decomposition Reactions

Question 5

Types of Chemical Reactions:
-one element replaces a similar element in the compound (e.g. Daniell Cell)

Answer 5

Single Displacement Reactions

Question 6

Types of Chemical Reactions:
-predicts whether single displacement reactions proceed or not

Answer 6

Activity Series

Question 7

Types of Chemical Reactions:
-occurs when two ionic substances react and exchange ions with one another

Answer 7

Double Displacement Reactions

Question 8

processes where reactants, (the starting materials) are transformed into new materials or substances

Answer 8

Products
