Define chemical reaction
The rearrangement of the atoms and bonds in one set of molecules to form a different set of molecules
define limiting reagent
The limiting reagent in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
what is the equation for molarity?
mols/L
what does gel electrophoeisis separate proteins based on?
charge and size
What is the molar mass of C6H12O6?
180.156 g/mol
What does a balanced chemical equation describe?
The quantitative relationship between the number of the reactant molecules and product molecules
Looking at the following equation, if you have 1 mol of N2 and 1 mole of H2, what is the limiting reagent?
1 N2 + 3 H2→ 2 NH3
H2
What equation do you use for dilution calculations?
C1V1=C2V2
What is the stain we use to see the proteins in gel electrophoresis called?
Methylene Blue
How many micro L are in one mL?
1000 micro L are in one mL
Balance the chemical equation for glucose metabolism:
C6 H12 O6 + O2 → CO2 + H2O
C6 H12 O6 + 6O2 → 6CO2 + 6H2O
Looking at the following equation, if you have 1 mol of N2 and 3 mole of H2, what is the limiting reagent?
1 N2 + 3 H2→ 2 NH3
both are limiting
___ is the substance being dissolved while __ is the dissolving medium

What is the amino acid that helps the proteins hook onto the resin beads called?
Histidine
How many mols is 5.00g NaCl?
0.08556 mols NaCl
Balance the following chemical equation
C3H8 +O2 → CO2 + H2O
C3H8 + 5O2 → 3CO2 + 4H2O
Looking at the following equation, if you have 1 mol of N2 and 2 mole of H2, how many moles of NH3 are produced?
1 N2 + 3 H2→ 2 NH3
1.333
(2 mol H2) x [(2 mol NH3) / (3 mols H2)] = 4/3 NH3 or 1.333
What volume of a given 10 mM stock solution is required to make 20 mL of a 5mM solution?
10 mL
What type of reaction happens between the histidine and the Ni2+ ions on the resin beads?
Ion dipole
what is the room number for where we meet before lab?
255
Balance the following equation
C4H10 + O2 → CO2 + H2O
2C4H10 + 13O2 → 8CO2 + 10H2O
What does the slope on a limiting reagent graph represent?
molar ratio
what is the difference between molarity and concentration?
concentration is the ratio of the amount of solute per amount of solution. Meanwhile, molarity is a unit of concentration that relates the amount of moles of a solute per liter of solution.
Who invented gel electrophoresis?
Arne Tiselius
