What are Chemical Reactions?
  • nature and identity of initial substance changes
  • so, whenever a change occurs, a chemical reaction occurs

When a chemical reaction takes place, the following happens

  • change in state of the initial object (solid, liquid, gas)
  • change in color
  • evolution of a gas ( as a result of the reaction)
  • change in temperature
