Answer to Question #205218 in General Chemistry for Chloe Burridge

Question

Consider the unbalanced chemical reaction:  KO2 (s) + H2O(ℓ) →  KOH (s) + O2 (g) . 

If 10.70 g of KO2 and 1.80 g of H2O are reacted together:

a) What is the limiting reagent?

b) What mass of O2 can be produced?

 

 

c) Assuming the reaction takes place in a 1L vessel and the temperature is controlled at 25℃, what will the pressure of the vessel be?

 

d) If 2.22g of O2 is produced, what is the percent yield of the reaction?

Answer 1

a) Limiting reagent=$KO_2$

b) Mass of O2 produced=12.96g

c)Pressure of the vessel=2.3atm

d) percent yield of the reaction=73.4 %
