How many moles of HCL must be added to a liter of buffer that is 1.5M in acetic acid and .080M in sodium acetate to result in a buffer solution that is 4.11 in pH

Butanoic acid (Ka=1.54E-5) with 0.100M NaOH solution after the following additions of the titrant.

A) 11 mL

B) 20.90 mL

C) 25.00 mL

Find the pH of a titration of 40mL of .1000M HCL with .1000M NaOH solution after the following additions of base.

A) 23mL

pH=

B) 39.8mL

pH=

C) 51.00mL

pH=

Thank you!! I can't figure this out to save my life!!

Three gases, nitrogen, helium, and methane are confined in a 4.00 L vessel at a pressure of 6.00 atm. The vessel contains 3.00 moles of nitrogen, 3.00 moles of helium, and 3.00 moles of methane. What is the partial pressure of methane?

Partial pressure of methane = atm

Now suppose that 3.00 moles of neon are added to the vessel without changing the volume or temperature. What is the partial pressure of methane now?

Partial pressure of methane after addition of neon = atm

Now suppose that an additional 3.00 moles of methane are added to the vessel, again without any change in the volume or the temperature. What is the partial pressure of methane now?

Partial pressure of methane after addition of 3.00 more moles of methane = atm

Single or double bond?

i found the dress, the tights and thank god the body and face paint.

all i need now is a way to set the paint so it won't totally come off...

i sent this message to my boyfriend becasue he makes no effort to talk to me

okay so some things have been bugging me and i just need to know how into this whole thing you are. I'm a girl i think things over extensively and i might just be over reacting but then again i might be right.

okay well its been bugging me that we never ever talk. i know that we have extremely busy summers but doesn't something seem kind of wrong here? and i know we've been gone and such but we don't even TALK not even see each other but just talk to each other. i miss you and sometimes i doubt if the feeling is mutual.

okay well and one last thing.

please let me know exactly how you feel, firstly i'm your friend and also i kinda am REALLY curious as to whats going on up there.
