Write the conjugate acid formula of Ammonia.
NH3 + H+ ----> NH4+
If you start with 1 mol of carbon with excess oxygen, what is the theoretical yield of CO2 in grams?
C(s) + O2 (g) ---> CO2 (g)
If an experiment actually produces 33 grams of CO2, what is the percent yield?
Theoretical Yield: 44 g of CO2
Percent Yield: 75%
What is a limiting reagent?
Substance that runs out first in a chemical equation.
What is a redox reaction?
A redox reaction (short for oxidation-reduction reaction) is any chemical reaction in which the oxidation states of the atoms change through the transfer of electrons between two species.
A boy lost his dog to a tragic street strike,
So he used stormy lightning to give it new life.
First a short film, then stop-motion complete—
Name this sparky young pup who returned for a treat!

Write the conjugate acid formula for the carbonate ion.
CO3-2+ H+----> HCO-3
In a lab experiment 2 mol of H2 reacts with excess oxygen to produce water.
2H2(g)+O2(g)----> 2H2O(l)
Calculate the theoretical yield of H2O in grams!
36.04 g H2O
Name the acids H2SO4 and H2CO3
What is oxidation and reduction?
Oxidation: The loss of electrons
Reduction: The gain of electrons
I ruled over Halloween, dark and polite,
Till I stumbled on presents and trees filled with light.
I traded my bones for a red velvet suit—
Who am I, bringing holiday loot?

Write the formula for the conjugate base of Nitric Acid
HNO3---> H++NO-3
A Chemist reacts 54 grams of Al with excess oxygen.
4Al(s) + 3O2(g) ---> 2Al2O3(s)

Percentage Yield: 83.3%
When I dissolve in water, I dissociate or ionize essentially 100% completely into freely mobile, charged entities. Because of my complete breakdown, I allow electric current to flow easily and make conductivity light bulbs shine brightly
Strong electrolyte.
Write the oxidation numbers for
Cu(s) + 2Ag+(aq)---> Cu+2(aq) +2Ag(s)
Which one is being oxidized and which one is being reduced
Oxidized: Cu
Reduced: Ag
By the side of the river, my white dress is torn,
I wander the midnight, heartbroken and forlorn.
I search for the children I lost to the deep—
What phantom am I, making night-dwellers weep?

write the conjugate acid and base of HPO-24
Conjugate Acid:H2PO-4
Conjugate Base: PO-34
TiCl4(g) + 2Mg(s) ---> Ti(s) + 2MgCl2(s)
A reaction vessel is charged with 190 g of TiCl4 and 60 g of Mg Identify the limiting reactant. Calculate the theoretical yield of titanium (Ti) in grams.
Limiting Reactant is TiCl4
Theoretical yield = 47.97 g Ti
AgNO3(aq)+NaCl (aq) --->
Write the ionic and net ionic equation INCLUDE IONS AND CHARGES!
Total Ionic
Ag+(aq)+ NO3-(aq) + Na+(aq)+Cl-(aq)---> AgCl(s) + Na+(aq) + NO3-(aq)
Net Ionic:
Ag+(aq)+ Cl-(aq)---> AgCl(s)
Find oxidation numbers to MnO-4
Mn = +7
O= -2
If you stand in the dark in front of a glass,
And whisper my name thirteen times as hours pass,
My bloodied, scratched reflection will appear in the light—
What ghost in the mirror causes slumber party fright?
Find the products of this formula & determine your conjugate acid and base.
HNO3 + H2O --->
HNO3 + H2O ----> H3O+ + NO3-
Conj Acid: H3O+
Conj Base: NO3-
What causes percent yield to be over 100%?
A calculated percent yield greater than 100% cannot occur by creating matter out of nothing, as that would violate the Law of Conservation of Mass
PUUUUUUUUUUUUUUUMPKIIIIIIIIIIIINNNNNNNNNNNN
MnO2 (s) + 4HCl (Aq) ---> MnCl2 (aq) + Cl2 + 2H2O
Write the oxidation numbers and determine which is being oxidized and reduced. Find the oxidizing and reducing agents.
Oxidized: Chlorine
Reduced: Manganese
Reducing Agent: Cl
Oxidizing Agent: Mn
With glowing red eyes and a thirst for the night,
I stalked through the farms, giving livestock a fright.
No blood in the goat when the morning sun rose—
What cryptid of rumor made whole towns freeze close?
