Based on the observation that the beaker gets warm to the touch as the reaction progresses, it can be inferred that the reaction is exothermic (Option d).
To determine the type of reaction based on the observation that the beaker gets warm to the touch as the reaction progresses, you need to understand the concepts of exothermic and endothermic reactions.
An exothermic reaction is a chemical reaction that releases heat energy into the surroundings. This means that the system loses energy, and the surroundings gain energy. As a result, the surroundings, in this case, the beaker, may become warmer.
On the other hand, an endothermic reaction is a chemical reaction that absorbs heat energy from the surroundings. This means that the system gains energy, and the surroundings lose energy. In this case, the beaker would feel colder rather than warmer.
Given that the beaker gets warm as the reaction progresses, we can conclude that the reaction is exothermic. Therefore, the correct answer is d. exothermic.
