Given the following balanced equation, which is NOT a correct conversion factor? 4 NH3 + 5 O2 → 4 NO + 6 H2O

1. 18.02 g H20 = 1 mol H2O

2. 5 mol O2 = 4 mol NO

3. 1 mol NH3 = 17.03 g NH3

4. 5 mol O2 = 32.00 g O2

How many molecules are found in 1.32 mol of nacl?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.

How many liters of 3.0 m naoh solution will react with 0.60 liters of 4.0 m h2so4? h2so4 + naoh → na2so4 + h2o 1.2 l 1.6 l 2.4 l 2.8 l
