Sorry, I'm don't really understand question 2.
"–PoppΔV = �?9.86923 atm)(0.020 L) = �?.197385 L atm"
where the 0.02L come from. I though that is number of moles, and -20J isn't one of the options in the question.
I came across two acid and base equations last nigh, pretty similar but I can't do them. I think I have some problems with writing out chemical equation and the ICE table, could you help me with these two also?
10.3 mL 0.200 M nitric acid solution is added to 50.00 mL 0.100 M sodium hydroxide solution. What is the pH of the solution?
24.2 mL 0.200 M nitric acid solution is added to 50.00 mL 0.200 M ammonia solution. What is the pH of the solution? (Kb for ammonia 1.80 x 10-5)
Sorry for the trouble. |
