Answer
Ratio of moles of reactants and products in a balanced equation.
8
Question
What is a solute?
Answer
Substance dissolved in a solvent.
9
Question
What is a solvent?
Answer
Substance in which a solute dissolves.
10
Question
What does soluble mean?
Answer
Capable of being dissolved in a solvent.
11
Question
What does insoluble mean?
Answer
Incappable of dissolving in a solvent.
12
Question
What is dissolution?
Answer
Process of a solute mixing with a solvent to form a solution.
13
Question
What is a precipitation reaction?
Answer
Two soluble substances form an insoluble solid.
14
Question
What is a precipitate?
Answer
The solid formed in a precipitation reaction.
15
Question
What is solubility?
Answer
Extent to which a substance dissolves in a solvent.
16

Ion that does not participate in the reaction.
17
Question
What is precipitation gravimetry?
Answer
Analytical method using precipitate mass to determine quantity.
18
Question
Why are repeat trials important in precipitation gravimetry?
Answer
To reduce random errors and increase reliability.

Answer
Variations around true value due to unpredictable factors.
21
Question
What is systematic error?
Answer
Consistent deviation from true value due to instrument/procedure.
22
Question
What does accuracy measure?
Answer
How close a value is to the true value.
23
Question
What is particle theory?
Answer
Matter composed of small indivisible particles in motion.
24
Question
What is collision theory?
Answer
Reaction rate depends on particle collisions with correct orientation/Energy.
25
Question
What is rate of reaction?
Answer
Change in concentration of reactants/products over time.
26
Question
What is conservation of mass?
Answer
Mass is conserved in chemical reactions.
27
Question
Name a method to measure rate of reaction.
Answer
Mass change, colour change, or volume of gas.
28
Question

Answer
Concentration, surface area, temperature.
29
Question
What is activation energy?
Answer
Minimum energy required for effective collisions.
30
Question
How does concentration affect rate?
Answer
Higher concentration increases collision frequency and rate.
