**Question 3:**"A log burns in a fireplace, warming the room. Is this an exothermic or an endothermic reaction? Acid-base reaction? Precipitation reaction? Redox reaction? Gas evolution reaction? Combustion reaction? Combination reaction? Dissociation reaction?"---**Explanation:**When a log burns in a fireplace, it undergoes a chemical reaction that releases energy in the form of heat, warming the room. This type of reaction is specifically a combination of:- **Exothermic Reaction:** This is a type of reaction where energy is released into the surrounding environment, thus heating it up. As the log burns, it produces heat, demonstrating that it's an exothermic process.- **Combustion Reaction:** This is a type of exothermic reaction where a substance (in this case, the log) reacts with oxygen, producing heat and often light. The burning of the log is a clear example of combustion, where the chemical energy stored in the log is converted into thermal energy.Additionally, combustion is a form of **Redox Reaction** where the log (fuel) is oxidized, resulting in the reduction of oxygen, and it also can be considered part of a **Gas Evolution Reaction** due to the production of gases like carbon dioxide (CO₂) and water vapor (H₂O).The provided question lists several types of reactions, but specifically, the burning of a log in a fireplace is not an Acid-base reaction, Precipitation reaction, Combination reaction, or Dissociation reaction.

When a log is burning in presence of oxygen, it evolves heat. Acid base reaction where one axid…
