-         losing electrons oxidized

-         gaining electrons reduce

-         oxidize species

Definitions:

Oxidizing agent- reduced ( gains electrons)

 Reducing agent- Oxidized ( gains electrons)

Corrosion-  is the process whereby a metal deteriorates

Electrolysis- use of electrical energy to produce chemical change

-         Know the format

HCl

HNO3

H2SO4

• chapter 26

-         corrosion is the process whereby a metal deteriorates and combustion is  an oxidation reduction reaction between a nonmetallic material and molecular oxygen.

-         The salt bridge permits the flow of electrons through the conducting wire creating an electric circuit.

LEO the lion went GER

-         losing electrons oxidized

-         gaining electrons reduce

When they say a strong base means the more readily it accepts hydrogen ions.

Questions-  If u want to change an element, is it possible?

                    How do you create an element? How do you change an element?

Answer- By adding protons

Question- what makes an element distinct?

Answer- The amount of protons : atomic number

Question- is there an atom heavier than hydrogen???

Answer- YES. All of the elements are heavier than hydrogen

Question- How would you know an element is heavier?

Answer: Atomic mass or atomic weight

Question: The Bohr Model of the atom is similar to what?

Answer: the solar system

Question: What is Brownian Motion?

Answer: Perpetual jiggling of particles

Definitons-

Covalent compound- electrical attractions in which atoms are held tightly together

Alloy- a mixture of 2 or more metallic elements

Ionic compound- chemical compounds containing ions

Question- what is the difference between a solution and a suspension?

Answer- a solution has a same phase and a suspension has different phases.

Question- what is a concentrated solution???

Answer- a concentration solution is the amount of solute dissolved per amount of solution.

Question: What is a molecule and how are soaps and detergents different? Why does oxygen have low solubility in water?

Answer: Detergents have a stronger grease penetration and a lower price and soap molecules have nonpolar and polar properties.

itz tight as hell..

havent updated for a while cuhs i was lazy...hmm lets see... schools ok...im getting ok grades except i think  im failin science and history ...but other than that i think im doin pretty good.. but imma try to get good grades this year, reachin for a gold, if not than silver.
