Question

1. 2C8H18+25O2------>16CO2+18H2Ohow many moles of CO2 are emitted into the atomosphere when 17,6 g of C8H18 is burned2. complete this reaction to show how pyridine, C5H6NH acts as a Bronsted-Lowry base in waterC5H5N+H2O------C5H6NH+ +OH-3.calculate either H3O+ or OH- for the solutions below at 25 degrees C. OH- =2.87x10 (-7) M H3O- _______M H3O+=8.33x10 (-9) M OH- =_________M H3O+=0.000623 M OH- = _________M PH=1.0x10(1) H3O+ =_________M4. What are the concentrations of H3O+ and OH- in oranges that have a PH of 3..80? H3O+ = _________M OH- = __________M5. Classify each solution as acidic, basic or neutral in an aqueous solution of 25 degrees C.Ph=2.65H+ =9.1x10(-3)OH- =9.7x10(-2)Ph=9.30H+ =7.3x10(-11)OH- =2.3x10(-13)PH=7.0H+ =1.0x10(-7)
