Complete #2a on page 1, #5 & 6 on page 2, and #1a & 2a on page 3.

Sections 9, 10 & 11: Complete the following:

1) Given the following equation: Na2O + H2O ---> 2 NaOH


a. How many grams of NaOH is produced from 1.40 x 102 grams of Na2O?
b. How many grams of Na2O are required to produce 1.20 x 102 grams of NaOH?

2) Given the following equation: 2 NaClO3 ---> 2 NaCl + 3 O2

a. 24.00 moles of NaClO3 will produce how many grams of O2?
b. How many grams of NaCl are produced when 80.0 grams of O2 are produced?

3) Given the following equation: Cu + 2 AgNO3 ---> Cu(NO3)2 + 2 Ag

a. How many moles of Cu are needed to react with 3.50 moles of AgNO3?
b. If 89.5 grams of Ag were produced, how many grams of Cu reacted?

4) The average human requires 120.0 grams of glucose (C6H12O6) per day.  The photosynthetic reaction is: 6 CO2 + 6 H2O ---> C6H12O6 + 6 O2

a. How many grams of CO2 (in the photosynthesis reaction) are required for this amount of glucose?

**Note that #5 is a multiple choice problem**
5) Given the reaction: 4 NH3 (g) + 5 O2 (g) ---> 4 NO (g) + 6 H2O (l)
