2. Where the electric current enters/leaves a battery cell: Terminal.
3. O2's part in the reaction: C5H12 + 8O2 → 5CO2 + 6H2O: Oxidizing agent.
4. When a substance has lost electrons during a chemical reaction it is: Oxidized.
5. When a large organic molecule has gained hydrogen, it is: Reduced.
6. A material that conducts electricity: Conductor.
7. The process of breaking down through the use of electricity: Electrolysis.
8. Opposite of conductor: Insulator.
9. Is attracted to the cathode: Cations.
10. Is attracted to the anode: Anions.
11. The process of covering a metal object with another metal through the use of electricity: Electroplating.
12. Conducts electricity when molten/dissolved in water: Electrolyte.
13. The negative electrode: Cathode.
14. The positive electrode: Anode.
15. The oxidized substance in the photosynthesis reaction: Water (H2O).
16. Aluminum oxide needs to be order to be electrolyzed in molten Cryolite: Dissolved.
17. Cu → Cu+2+2e for example: Oxidation half-reaction.
1. Cellular respiration is the process by which glucose is broken down in cells to produce energy. Glucose molecules undergo a series of chemical reactions, ultimately yielding ATP, the cell's primary energy source.
2. In a battery cell, the terminal is where the electric current enters or leaves. It acts as the connection point between the external circuit and the internal chemical reaction occurring within the battery.
3. Oxygen (O2) serves as the oxidizing agent in the reaction: C5H12 + 8O2 → 5CO2 + 6H2O. It accepts electrons from the reactant (C5H12) during oxidation, facilitating the combustion process.
4. When a substance loses electrons during a chemical reaction, it undergoes oxidation. This loss of electrons results in an increase in the substance's oxidation state or positive charge.
5. When a large organic molecule gains hydrogen atoms, it is undergoing reduction. Reduction involves the gain of electrons or a decrease in oxidation state, often accompanied by the addition of hydrogen atoms.
6. Conductors are materials that allow the flow of electricity. They possess free-moving electrons that facilitate the transmission of electric current.
7. Electrolysis is the process of breaking down a compound into its constituent elements using electricity. It involves passing an electric current through an electrolyte to induce chemical reactions.
8. Insulators are materials that inhibit the flow of electricity. They have tightly bound electrons, making it difficult for electric current to pass through them.
9. Cations are positively charged ions attracted to the cathode, the negative electrode, during electrolysis. They move towards the cathode to gain electrons and undergo reduction.
10. Anions are negatively charged ions attracted to the anode, the positive electrode, during electrolysis. They move towards the anode to lose electrons and undergo oxidation.
11. Electroplating is the process of depositing a metal coating onto a metal object using electricity. It involves immersing the object in a solution containing ions of the coating metal and passing an electric current through it.
12. Electrolytes conduct electricity when dissolved in water or molten, as they dissociate into ions that facilitate the flow of electric current.
13. The cathode is the negative electrode in an electrolytic cell. It attracts cations, where they gain electrons and undergo reduction reactions.
14. The anode is the positive electrode in an electrolytic cell. It attracts anions, where they lose electrons and undergo oxidation reactions.
15. In the photosynthesis reaction, water (H2O) is the oxidized substance. It loses electrons and undergoes oxidation to release oxygen gas (O2), which is a byproduct of photosynthesis.
16. Aluminum oxide needs to be dissolved in molten cryolite to be electrolyzed efficiently. Cryolite acts as a solvent and lowers the melting point of aluminum oxide, facilitating the electrolysis process.
17. The equation Cu → Cu+2 + 2e represents an oxidation half-reaction, where copper (Cu) loses two electrons to form copper ions (Cu+2). This process is an example of oxidation, as copper undergoes an increase in oxidation state.
