|
Explain the importance of chemistry to the study of life
|
Chemistry is the base of biological structure.
|
|
|
Distinguish between electrons, neutrons, and protons, atomic mass and atomic number
|
Mass = Protons & Neutrons: Atomic# = Protons: Electrons have a single negative charge; Protons have a single positive charge: Neutrons have no charge
|
|
|
Determine the term isotope and an application that uses a radioactive isotope
|
They have protons and neutrons, but have a different number of electrons; An Application would be Carbon14 and carbon dating
|
|
|
What are valence electrons and how are they related to the bonding behavior of atoms?
|
They are the electrons that are level of energy atoms and their levels are how they bond.
|
|
|
What are the 4 main types of bonds
|
Ionic - Steal / Covelant - share / Non-polar - Equal sharing / Polar - equal sharing / Hydrogen - sharing of neighboring molecules
|
|
|
The characteristics of water that result from hydrogen binding
|
Cohesion - sticking of molecules together / Adhesion - sticking to a surface / Surface Tension - how easy or hard to stretch or break the surface of a liquid
|
|
|
What is a solution, solute, and solvent?
|
Solution - 2 or more substances / Solute - The substance being dissolved / Solvent - The dissolving agent
|
|
|
How are acids and bases capable of changing the hydrogen concentration of a solution?
|
Because the water can break apart in aqueous solutions into ions, adding or subtracting H+ molecules.
