What is intermolecular force?
Force between molecules.
What pH was the ocean before the industrial evolution and what is it at now?
8.4-->8.1
What is an Arrhenius Acid?
Substance the produces Hydrogen Ions (Protons) in Aqueous Solution.
What is a Limiting Reactant
Reactant that limits/restricts the amount of products that can be formed
What is a Single Displacement Reaction
Chemical reaction where one element is exchanged with another element in a compound
What is intramolecular force?
Force within the molecules.
Why is Ocean acidification not accurate
The ocean becomes more neutral, not more acidic
