(if you use it litmus is one property)
Acids:
always soluble in H2O

reacts with metals to produce H2(g)
Aqueous
When they are dissolved in water, we say they “ionize"
Bases:
usually soluble in H2O
conducts electricity
neutralize acids
taste bitter
feel slippery
Are usually ionic hydroxides (ie. contain OH- ion).
When they are placed in water we say they “dissociate”

What subatomic particles are located within:
1. in the nucleus
2. in the cloud region (within energy levels)
Also what charges do each type of subatomic particle have?
On the periodic table -
How do you find the number of:
Electrons, Protons and Neutrons
Give me an Example!
1. Neutrons (Neutral) & Protons (Positive)
2. Electrons (Negative)
Electrons = The Atomic Number
Protons = The Atomic Number
Neutrons = The Atomic Mass - The number of Protons
Aluminium:
Electrons = 13
Protons = 13
Neutrons = 26.98-13 --> 13.98 --> 14

(NH4)3PO4 (aq) + Ba(OH)2 (aq) --> NH4OH (aq) + Ba3(PO4)2 (s)
300
Why do Cations give up their extra electrons, or why do Anions accept extra electrons when they are in their ionic state?
Because they are trying to fill/empty their valence shell. Elements with complete valence shells (the noble gases) are extremely stable, ions donate/accept electrons to try and achieve that stable configuration!

Name the following compounds:
C12H22O11 & Na2SO4
1. sucrose
2. sodium sulfate

Explain the Naming Rules for Acids & Bases
Acids
1. Name compound as an ionic compound
- Hydrogen ______ide --> Hydro___ic Acid
- Hydrogen ______ate --> _______ic Acid
- Hydrogen ______ite --> ______ous Acid
*STATE IS ALWAYS aq
Bases: same rules as ionic compounds because most bases are ionic except ammonia - NH3
1. The Cation stays the same
2. OH = Hydroxide
NaOH = Sodium Hydroxide
300
How many molecules are present in 0.75 mol of H2O?
# atoms = n x Avogadro's #
0.75 mol x 6.02 x 1023 = 4.515 x 1023 -->
~4.5 x 1023 molecules are present in 0.75 mol of H2O

What do Elements in the same group (ignoring the 1 in groups 13-18) have in common?
All non-metallic ions:
a. have fewer electrons than protons
b. have more electrons than protons
c. have more protons than electrons
d. have less protons than neutrons
They have the same number of valence electrons!
b. more electrons than protons! Non-metal ions have a net negative charge, which means they have more electrons than protons!

CH4 burns in air to provide fuel for a natural gas barbecue
CH4(g) + 2 O2(g) --> CO2(g) + 2 H2O(g)
Air = distractor
Fuel = CO2 --> Hydrocarbon combustions always produce CO2 (g) + H2O (g)

Name the Ion for the following elements:
Na, Ir, Ge & F
What are the Diatomic & Polyatomic Molecules (Formulas!)
--> Bonus 100 points if you can tell me when they are in their diatomic, polyatomic state
Na2+ = Sodium Ion
Ir4+ = Iridium Ion
Ge4+ = Germanium Ion
F- = Fluoride Ion
H2, N2, F2, O2, I2, Cl2, Br2, P4, S8
Bonus - They are in this state when they are alone!
Example: CH4 does not follow the rule of H2, because Hydrogen is not on its own (it's bonded to Carbon)
"Produces hydrogen gas" follows the rule of H2 (g) because Hydrogen is on it's own (not bonded to anything)

Where do electrons exist? What happens to an electrons position when they gain or lose energy?
1. Alkali Metals 2. Halogens 3. Alkaline Earths
4. Metalloids 5. Transition Metals 6. Noble Gases
Classify the elements below with the names in the list above
rubidium is an example of a(an)____________
strontium is an example of a(an)____________ xenon is an example of a(an)____________
iodine is an example of a(an)____________
Electrons orbit the nucleus at specific distances, inside specific energy levels!
- Electrons that absorb (gain) energy can be be temporarily excited to a higher energy level, and they emit (lose) energy as they return to their original level.
Rb = Alkali Metal (Group 1)
Sr = Alkaline Earth Metals (Groups 2)
Xe = Noble Gas (Group 18)
I = Halogen (not a gas though!)

Why is it necessary for us to Balance chemical equations? (looking for a specific concept in the answer)
Because the Law of Conservation of Matter states that matter cannot be created or destroyed, only transferred or transformed. This means in a chemical reaction the number of element s & the total mass of reactants and products needs to be equal!
