Unit 2.2 Flashcards
What is the main difference between inorganic an organic molecules?
Inorganic molecules mostly do no contain carbon, only certain exceptions like H2CO3.
What is the usual type of bond and size for inorganic molecules?
Small and have mostly ionic bonds but also covalent bonds.
What are organic molecules?
Molecules that contain Carbon and Hydrogens, large and complex. They have covalent bonds.
What are the four examples of organic molecules?
Carbohyd, Proteins, Lipids and Nucleic Acids(RNA/DNA).
What certain liquid molecule tends to dissociate into ions?
Water into H+ and OH-.
What is Acids?
A substance that dissociates in water and increases H+ ion concentration which causes liquid to be more acidic
What is a base?
A substance that dissociates in water and decreases the H+ ion concentration which makes the liquid become more alkiline or basic.
How does the pH scale work?
The smaller the number the more acidic, the larger the number makes it most basic. If it’s seven, then substance is neural.
If pH in solution A is 5 and in second solution B is 7 how many MORE times is solution A more acidic to solution B?
x1/100 times more.
What are the small Legos considered as?
Monomers.
What are the three important buffers?
Bicarbonates(blood), phosphate(ATP), proteins(amino acids).
What are buffers?
Liquids that prevent change in pH, they can remove or replace H+ ions. Blood is. buffer.
What do salts disolve into?
Cations or anions.
KCl + H2O –> K+ + Cl-
What happens during neutralization reactions?
Acids + base –> salt + water
HCl + NaOH –> H20 + NaCl
What are electrolytes?
Salts tht conduct electical currents.
Na+
