H2 + O2 ---> H2O2
reactants: H2 & O2
Products: H2O2
element: H is an element (H2 is a molecule of 2 H atoms but would be considered an element as well), O is an element (same reasoning O2 would be considered an element)
compound: H2O2
Explanation:
- your reactants are the molecules or atoms you have to create the desired product (what you have before the reaction occurs)
- your products are what is created by the reaction
- element is mostly explained above
- compound is a molecule containing more than one element
