Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Determine the reaction type: $2KClO_3 \rightarrow 2KCl + 3O_2$.

Answer: Decomposition reaction. Potassium chlorate breaks down when heated.

Flashcard 2: Which option best describes an oxidation reaction?

Answer: Loss of electrons by a molecule, atom, or ion. Increase in oxidation state occurs.

Flashcard 3: Which type of reaction involves electron transfer?

Answer: Redox reaction. Electrons are transferred between reactants.

Answer: Neutralization reaction. Acid plus base forms salt and water.

Flashcard 18: What is the role of a reducing agent in a redox reaction?

Answer: Donates electrons and becomes oxidized. Loses electrons while reducing another species.

Flashcard 19: What defines an endothermic reaction?

Answer: Absorbs energy from the surroundings. Heat is absorbed during the reaction process.

Flashcard 20: Identify the reaction type of $CaCO_3 \rightarrow CaO + CO_2$.

Answer: Decomposition reaction. One compound breaks into two products.
