• Synthesis

In a decomposition reaction, what happens to a single compound?

• It combines with another compound

• It breaks down into two or more simpler substances

• It exchanges ions with another compound

• It reacts with oxygen to produce CO2 and H2O

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

• It slows down the reaction

• It combines with the reactants

• It speeds up the reaction without being consumed

• It changes the products of the reaction

What are the products of the decomposition of water using electrolysis?
