What are some characteristics of acids?
200
Acetates, alkali metals, ammonium, Bromides, Chlorides, nitrates, and Sulfates.
Which compounds are soluble in water (in general)?
200
A sample of matter, either a single element or a single compound, that has definite chemical and physical properties?
What is a pure substance?
200
Heat and water are released through this reaction.
What is released during a combustion reaction?
200
: An ionic compound that forms when a metal atom or a positive radical replaces the hydrogen of an acid.
What is a salt?
200
They ionize completely whilst these only release few hydrogen ions in aqueous solutions.

What is a molecule?
400
A reaction in which a single compound breaks down to form 2 or more simpler substances.
What is a decomposition reaction?
400
An ion made of 2 or more atoms.

What is the difference between homogeneous and heterogeneous mixtures?
500
A series of elements that have similar properties and that are arranged in descending order of chemical activity.
What is the activity series?
500
They do not consist of molecules, but they are strong and have distinctive properties.
What are some characteristics of ion compounds?
