In a displacement reaction, an element reacts with a compound. For example, two molecules of carbon (2C) might react with one molecule of
silicon dioxide (SiO2). The element takes the place of one of the elements
in the compound, displacing it. In this case, the carbon bonds with the
oxygen, taking place of the silicon. The products are Si and 2Co.
Which of the following best summarizes what happens in a displacement reaction?
A
Two elements react to form a compound.
B
A compound breaks down into elements.
с
An element and a compound react to form a different element and compound
D
An element and a compound react to form another compound.
