Chapter 4

Question 1

chemical reaction

Answer 1

reactants –> products

look for: color change, formation of a solid (precipitate), evolution of a gas, evolution/absorption of heat

Question 2

REMEMBER TO BALANCE EQUATIONS

Answer 2

that is all

also remember to put the state of matter

Question 3

reaction conditions

Answer 3

written above/below the arrow

-delta (triangle) means a high temperature is required

Question 4

stoichoimetry

Answer 4

moles A x (stoichiometric coefficient of B)/(stoichiometric coefficient of A) –> moles B
stuff in the middle = stoichiometric factor

Question 5

solvent

Answer 5

where the reaction takes place

eg. aqueous solution = liquid water is solvent

Question 6

solutes

Answer 6

the stuff dissolved in a solvent

Question 7

molarity

Answer 7

M = n/V (moles/L)

Question 8

dilution

Answer 8

when a volume of a solution is diluted, the amount of solute remains constant
MiVi = MfVf

Question 9

theoretical yield

Answer 9

calculated quantity

Question 10

percent yield

Answer 10

actual/theoretical x 100

Question 11

intermediate

Answer 11

substance produced in one step and consumed in another step
