How to use (Consist, contain or include)

How to use (Consist, contain or include)
Contain and include both mean to have something inside or include something as a part. Consist of means to be made of or formed from something.
For example: The periodic table consists of rows and columns It contains elements. Different elements include carbon, sulphur, hydrogen, oxygen etc.


Each organ (roots, stems, and leaves) include all three tissue types (ground, vascular, and dermal). Different cell types consist of each tissue type.

Some Types of Inorganic Chemical Reactions (meaning)
Exercise 2
Read the following article. What is the meaning of the words in bold?
Elements and compounds react with each other in numerous ways. Almost every inorganic chemical reaction falls into one or more of four broad categories.
I. Combination Reactions
Two or more reactants form one product in a combination reaction. An example of a
combination reaction is the formation of sulfur dioxide when sulfur is burned in air:
S (s) + O2 (g) --> SO2 (g)
II. Decomposition Reactions
In a decomposition reaction, a compound breaks down into two or more substances.
Decomposition usually results from electrolysis or heating. An example of a decomposition
reaction is the breakdown of mercury (II) oxide into its component elements.
III. Single Displacement Reactions
Single displacement reactions are often subdivided into more specific categories, e.g., redox reactions -chemical reactions which involve oxidation and reduction.
IV. Double Displacement Reactions
In this type of reaction, elements from two compounds displace each other to form new compounds. An example of a double displacement reaction occurs when solutions of calcium chloride and silver nitrate react to form insoluble silver chloride in a solution of calcium nitrate.
