What is the Law of Conservation of Mass?


  •   The Law of Conservation of Mass states, “In any type of Chemical Reaction, mass cannot be created or destroyed.” This was a great discovery in Science as a whole. 

  • This proved that there was a fixed amount of mass in the universe and the mass could only be changed from one to  another form, not extricated or created.

What is an example of an Exothermic reaction?

Answers may vary

Wood Burning, Iron Oxide, etc

What is the law of Conservation of Energy?


  • The Law states that “Energy cannot be created or destroyed.”

  • This law became the first law of Thermodynamics and helped scientists to understand the different configurations of energy.

What is an example of an Endothermic reaction?

Answers May vary 

Melting Ice, Photosynthesis, conbustion, etc

What is the law of Conservation of charge?


  • The law states, “the net electric charge of an isolated system remains constant.”

  • In simpler terms, this means that any  systems not undergoing any form of chemical change will  never have a different charge.

Explain in Depth the difference between Exothermic and Endothermic reactions.

Exothermic-The suffix Exo mean outward or outside. An Exothermic Reaction is when a chemical reaction releases energy and causes the surrounding area to rise in kelvin.

Endothermic- This suffix Endo means within, which is a good translation of what it actually means. An Endothermic Reaction is when a chemical reaction absorbs heat from the surrounding habitual state. This means an Exothermic Reaction could hit the trigger for an Endothermic Reaction.
