A. Is this an exothermic or endothermic reaction.
It would be exothermic, right? Because energy is released?
B. If the two substances are defined as the system, what constitutes the surroundings?
What? System? Surrounding? I'm confused..
b. generally, the surroundings are everthing not in the system.
B. In a chemical reaction, the system refers to the substances undergoing the reaction, while the surroundings refer to everything outside of the system. In this case, the surroundings would include the glass beaker itself, the air surrounding the beaker, and any other objects or materials in close proximity to the beaker.
B. In chemistry, a system refers to the specific substances or chemical reactants that are the focus of our study or analysis. In this case, the two substances in the glass beaker would be considered the system. The surroundings, on the other hand, refer to everything outside of the system that can influence or be influenced by the system. In this particular scenario, the surroundings would include the air surrounding the beaker, any objects in close proximity to the beaker, or any potential heat exchange with the environment. The glass beaker itself can also be considered part of the surroundings, as it is influenced by the energy released in the reaction.
