Ok. I retyped the question straight from the book.hopefully its correct now.
Given the reaction 2 Na2 02 (s) + 2 H2o(i) —- 4 NaOH(s) + 02(g) I couldn't make out the symbol however its triangle H= -109 KJ determine the following reactions. 1. 16 Na2o2(s)+ 16 H2o(i)———- 32 NaOH(s) + 8 O2(g) 2. 2 NaOH(s)———— + 1/2
My apologies. I will type it over.
Ok thanks. What is the answer to the second one using CI
Ok thanks. 2.65 L O2 x (2 mols CO2/1 mol O2) = 2.65 x 2/1 = 5.30 L CO2. is this the correct answer?
How many liters of Co2(g) can be produced in the reaction of 5.24 L C O (g) and 2.65 L O2 (g) if all these gases are measure at the temperature and pressure? Thanks and My apologies
Thanks a lot.
So what is the answer?
Ok thanks for your help
