Front

What type of reaction is represented by the equation: 3 Pb + 2 H3PO4 -> 3 H2 + 1 Pb3(PO4)2?

Back

Single replacement reaction.

Front

What is the definition of a decomposition reaction?

Back

A reaction where one reactant breaks down into several products.

Front

What type of reaction occurs when two compounds exchange ions to form new compounds?

Back

Double replacement reaction.

Front

What are the products formed in complete combustion reactions?

Back

CO2 and H2O.

Front

Write the balanced equation for the combustion of octane (C8H18).

Back

2C8H18 + 25O2 -> 16CO2 + 18H2O.

Front

What is a synthesis reaction?

Back

A reaction where two or more reactants combine to form a single product.

Front

What is the general form of a combustion reaction?

Back

A hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What is the difference between a single replacement and a double replacement reaction?

Back

In single replacement, one element replaces another in a compound; in double replacement, two compounds exchange ions.

Front

What is the definition of a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a reaction without being consumed in the process.
