In a single displacement reaction, what happens to the single element?

• It takes the place of one element in a compound.

• It forms CO2 and H2O.

• It breaks down into simpler elements.

• It combines with another single element.

What is a double displacement reaction?

• A reaction that produces CO2 and H2O.

• A reaction where two elements combine to form a compound.

• A reaction where a compound breaks down into elements.

• A reaction where elements in two compounds switch places.

In a double displacement reaction, what happens to the elements in the compounds?

• They break down into simpler elements.

• They combine to form a new compound.

• They switch places with each other.

• They form CO2 and H2O.

What indicates a combustion reaction?

• The switching of elements in compounds.

• The breaking down of a compound.

• The presence of a flame.

• The formation of a new compound.

What are the products of a combustion reaction?

• Two elements

• Elements switching places

• A compound and an element

• CO2 and H2O
