stoich

Question 1

mole to particles/molecules/atoms

Answer 1

6.02 x 10^23

Question 2

mole to litre

Answer 2

22.4 L

Question 3

remember to

Answer 3

use sig figs

Question 4

limiting reagant (or reactant)

Answer 4

first reactant to run out during a chemical reaction, thing that produces the least amount of product

Question 5

excess reagant (or reactant)t

Answer 5

reactant that is left over after the chemical reaction stops, cheaper and easier to recycle, reactant that produces greatest amount of product

Question 6

theoretical yield

Answer 6

predicted amount of product, the smallest answer

Question 7

left over reagant/reactant

Answer 7

reactant given-reactant used = left over reactant

Question 8

actual yield

Answer 8

actual amount of product
less than theoretical yield

theoretical yield x percent yield = actual yield

Question 9

percent yield

Answer 9

a measure of the efficiency of a chemical reaction,

percent yield= actual yield/theoretical yield x 100
