Chapter 7

Question 1

reactants

Answer 1

the molecules on the left

Question 2

products

Answer 2

the molecules on the right

Question 3

if balancing really doesnt work

Answer 3

jsut use fractions and then get rid of them

Question 4

reaction stoicheometry

Answer 4

using the coefficients from teh reaction equation in ordeer to calculate moles of a product and or the reactant

Question 5

actual yield

Answer 5

the amount actually made

Question 6

theoretical yield

Answer 6

the amount the equation says that you will make.

Question 7

percent yield

Answer 7

actual/theoretical

Question 8

limiting reagent

Answer 8

is the reactant that is limiting the max amnount of produciton (gets used completely)

Question 9

find limiting reagent given grams of each

Answer 9

1. draw an equation
2. turn each into moles of the reactant
3. turn each into moles of the product
4. whichever one makes less is teh LR

Question 10

find percent yield given grams of each and actual yield

Answer 10

1. find LR
2. use the Lr to calculate the theo yield
3. the percent yield is equal to the act/theo

Question 11

given g of reactants, and the % yield find the actual yield

Answer 11

1. equation
2. limiting reactant and the theo
3. use algebra and the percent yield equation

Question 12

given actual yield in g, % yield find grams of reactant

Answer 12

1. equation
2. use percent yield to find theo
3. take it back to grams of reactant
