i need help on this chemistry

Question

1.SEP Engage in Argument from Evidence Discuss the flow of energy you observed in the reaction by describing a system and surroundings and the direction of energy flow. Include whether this reaction is exothermic or endothermic.



2.Does the amount of energy released or absorbed by the system increase or decrease as the amount of CaCl2 is increased (from reaction 1 to reaction 2)? Explain.

3.Consider a different chemical reaction, with different chemicals, than the one carried out in this experiment. If you ran this new chemical reaction and found that the temperature change was larger, to what would you attribute the difference?

Answer 1

C'mon Akjdf S.,

Is this your whole science review packet, verbatim?

P.S. If you are starting from "ground zero" on your science course, it would be much more efficient to find a live or Zoom tutor for 1-on-1 lessons.
