Explanation:</h3>
- Chemical reactions occurs when elements or compounds chemically join to form other compounds.
But, how do we know that indeed a chemical reaction has occurred?
- Chemical reactions involve changes of different parameters when they occur, thus various indications are used to show the occurrence of chemical reactions.
These indications include;
- Gas bubbles, also known as effervescence, for example when sodium metal is mixed with an acid, gas bubbles will be produced showing occurrence of a chemical reaction.
- Color change, which shows the formation of a new substance.
- Increase in temperature, which occurs in endothermic reactions where heat is absorbed from the surroundings.
- Decrease in temperature, which occurs in exothermic reaction where heat is lost to the surroundings.
- Other indicators include, formation of a precipitate, production of light, etc.
