What I Studied in Science Today

2nd Year Middle School: Completed photosynthesis ~ circulatory system as the scope for the mid-term exam. Pass 2: Oxidation-reduction reactions / Neutralization reactions. Oxidation: A reaction where a substance gains oxygen. Reduction: A reaction where a substance loses oxygen. They always occur simultaneously. So, examples include the reaction between copper(II) oxide and carbon, and the reaction of copper! Neutralization reactions can be summarized as Acid + Base -> Water + Salt.
