These two things are required for a reaction to occur.
What is activation energy and orientation?
100
The change in amount of a substance to make a reaction go faster
What is increasing concentration?
100
The guess of what will happen in an experiment
What is a hypothesis?
100
The ratio between products and reactants in a chemical equation.
What is stoichiometry?
100
A solid in aqueous solution is created.
What is a precipitate reaction?
200
This type of reaction is shown in this graph.
What is an exothermic reaction?
200
This is the area on a substance that can react with another substance. Increasing it will increase the reaction.
What is surface area?
200
The part of the experiment you are changing
What is the independent variable?
200
The grams per mole of a substance.
What is molar ratio?
200
This is a proton donor.
What is Brondsted-Lowry acid?
300
H2 + ICl --> HI + HCl (slow)
HI + ICI --> I2 + HCl (fast)
This is the proposed rate law.
What is Rate = k[H2][ICl]?
300
2CO(g) + 2NO(g) → 2CO2(g) + N2(g)
In this reaction, NO leaves the reaction at a specific pace.
What is the rate of disappearance?
300
You want to determine the impact of one thing on another. This is the part you measure.
What is the dependent variable?
300
I have 13 marshmallows, 13 graham crackers, and 13 full bars of chocolate. What is the limiting ingredient?
Chocolate

A solution of vinegar contains an unknown amount of , HC₂H₃O₂. A 25.0 mL sample of vinegar is titrated with 0.650 M NaOH according to the chemical reaction below. If it requires 32.04 mL of the NaOH to reach the equivalence point, what is the concentration of HC₂H₃O₂ in the vinegar?
0.833 M
400
H2 + ICl --> HI + HCl (slow)
HI + ICI --> I2 + HCl (fast)
HI is this.
What is an intermediate?
400
This increases the speed of a reaction but is not used up in the reaction.
What is a catalyst?
400
The different versions of your independent variable that you will test.
What are experimental groups?
400
2 NaCl + Pb(NO3)3 --> 2 NaNO3 + PbCl2
15.3 g of NaCl is reacted with 60.8 g of Pb(NO3)2?
This is the limiting reactant.
What is NaCl?
400
LEO stands for this
Loss of electrons is oxidation

If the y-axis of a graph is 1/[A] and the graph is linear, then this is the rate order.
What is 2nd order?
500
H2O2 + 2HI --> 2H2O + I2
When [H2O2] is 0.1 M and [HI] is 0.1 M, the rate of reaction is 0.0076 mol/Ls.
This is the value of k.
What is 0.8 M-1s-1?
500
Not the measured outcome, but something you can't do anything about
What are uncontrolled variables?

6.50 grams of aluminum reacts with an excess of oxygen. How many grams of aluminum oxide are formed?
4 Al + 3 O2 --> 2Al2O3
12.3g Al2O3
500
Al + Ni(NO3)2 --> Al(NO3)3 + Ni
This substance is reduced.
What is Ni?
