Study Notes
Chemical Reactions
- During a chemical reaction, the reacting substances (reactants) interact with each other, resulting in a transformation of one or more substances into new substances (products).
- The new substances produced as a result of a chemical reaction are called products.
- The atoms of one element are rearranged during a chemical reaction, but they are not created or destroyed; they are merely rearranged to form new substances.
- The substances that take part in a chemical reaction are called reactants.
- When a magnesium ribbon burns in air, magnesium oxide is formed.
Process of Chemical Reactions
- Chemical reactions involve the rearrangement of atoms to form new substances.
- The process of chemical reaction can be understood as a transformation of reactants into products.
Reactants and Products
- Reactants are the substances that participate in a chemical reaction.
- Products are the new substances formed as a result of a chemical reaction.
Example of Chemical Reaction
- An example of a chemical reaction is the reaction between magnesium and oxygen, forming magnesium oxide: 2Mg + O2 → 2MgO
Properties of Products
- The properties of the products formed in a chemical reaction are different from those of the reactants.
- The properties of the products are unique and depend on the new arrangement of atoms formed during the reaction.
