How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
