1) Write the balanced chemical equation for the decomposition reaction.
2) How many grams of carbon dioxide are produced?
3) How many grams of water are produced?
4) How many grams of diatomic oxygen are produced?
5) How many grams of diatomic nitrogen are produced?
6) The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Verify the law of conservation of mass for the decomposition of the 187.4 g of C3H5(NO3)3 .

Answer:

Answer:

Kc = 0.20        

Explanation:

                 N₂O₄     ⇄    2NO₂

moles       5.3mol          2.3mol

Vol               5L                5L

Molarity    5.3/5M        2.3/5M

               = 1.06M     = 0.46M

Kc = [NO₂]²/[N₂O₄] =  (0.46)²/(1.06) = 0.1996 ≅ 0.20
