Two substances in a glass beaker react chemically and the glass beaker becomes too hot to touch.
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..

  • Chemistry -

    a. correct
    b. generally, the surroundings are everthing not in the system.

  • Chemistry -

    the chemicals inside it reacts each other these energy trans fers to beaker and became hot when we touch it .
