A solution in equilibrium with solid barium phosphate is found to have a barium ion concentration of 0.0005 M and a Ksp of 6.59 x 10^-23. Calculate the concentration of phosphate ion. Answer in units of mol/L.

I'd really like some help on this. Please do not round. Just submit the entire number please. 5 stars for whoever gets it right! - Thanks.

What is the value of Ksp for Ag2SO4 if 5.60 g is soluble in 1.00 L of water?

I'd really like some help on this. Please do not round. Just submit the entire number please. 5 stars for whoever gets it right! - Thanks.

The ionization constant of acetic acid is 1.8 x 10^-5. What is the molar concentration of OH- ion in a 0.2 molar solution of sodium acetate?

thanks!

Calculate the percent ionization of a 0.56 molar solution of acetic acid. The ionization constant of acetic acid is 1.8 x 10^-5.

I will give 5 stars to who ever can answer this. - Thank you!

The pH of a 0.100 M solution of a weak acid HA is 3.65. Calculate Ka for the acid.

5 stars to whoever can answer this! Thanks!

Calculate the percent ionization of a 0.56 molar solution of acetic acid. The ionization constant of acetic acid is 1.8 x 10^-5.

I will give 5 stars to who ever can answer this. - Thank you!

What is the pH at 25C of a 0.32 M solution of the acid HClO which has an ionization constant of 3.5 x 10^-8?

I got 7.950781977 but I'm not sure if that's right.

5 stars to anyone who can do this! - Thank you.

Here's my question:

Sufficient SO3(g) is place in a 5.000 liter container, held at a constant, elevated temperature, to give an initial concentration of 0.200M.

2SO3(g) = 2SO2(g) + O2(g)

When the reaction comes to equilibrium, it is found that the concentration of O2 is 0.042 M. What is the numerical value of the equilibrium constant at this temperature?

I already did the problem and got an answer but I'm pretty sure it's not right. Can someone please work it out and explain? I will give ten stars! Thank you!

I understand that on the product side it is

CaO + P4O10

but I don't understand why the reactants are

Ca3(PO4)2

I will give five stars to the person who can explain why this is so and how you figure it out. Thanks!

KCl electrolyte

CO2 gas

Cl2 gas

There is no reaction.

or

FeCO3 precipitate

5 stars to whoever can answer and explain!!

I AM DESPERATE.

BaCl2 + Na2SO4

NaH + H2O

AgNO3 + CH3COONa

FeCl2 + Na2SO4

or

(NH4)2SO4 + KOH

I will give 5 stars to whoever can not only solve this but explain to me why and how to figure out that it will make a precipitate. Thank you!

Ok I am stumped on this question. The choices are:

1. B

2. Li

3.C

4.Br

5.S

If you know the right answer can you please explain why that is the answer as well? Thank you.

I'm currently bored and lucky to finally have some free time to bullshiit. So what are some great games online?

I love violent, cooking, girly, action and adventure games. Stuff like Robot Unicorn Attack and Happy Wheels are my favorites. So hit me up with some games please!

I thought that by downloading Google Chrome, I could just have it as my tool bar with Internet Explorer or does it not work like that? Is Google Chrome it's own internet browser? Or how can I get Internet Explorer back?

Ok for English class I need to write a 5 paragraph essay on this:

"Discuss how the use of the five different narrators in The Poisonwood Bible contributes to the development of the novel's various themes. Do not merely compare and contrast the narrators."

So can anyone tell me/give me ideas for the characters? Like what are the differences between them? Anything you can add in would be great!!

I would really appreciate this!!

I have a Toshiba laptop and the other day i spilled only a splash of water on the touch pad and on a few of the lower keys. the touch pad didnt stop working until a while after but the keyboard was fine. it wasnt until today that it stopedworking. i turned it on fine and was working all except the mouse. it wasnt until it froze and i restarted it that it stopped working. i restarted it again and again but still the same. i scaned it for viruses and i had none,

what should i do? i dont think it was the water since only a few keys got wet but now none of the keys work. please help!!

Yeah that's pretty much my question. Would really appreciate it! Thanks!

Just really curious about it since I have no idea. I keep hearing that he's Irish, of Hispanic decent, half Irish half Hispanic or half some other Caucasian and half Hispanic. UGH! Well what is he for real? He looks Italian to me but I don't know. Thanks in advance. Please provide proof or source!

I get bored at times so I like to play online games to pass the time. I've noticed that Asian games are the funnest online games. (Especially Japanese and Korean ones.) So does anyone know any fun Asian games? Like this one is one of my favorites http://www.arcadelady.com/playgame/11390/Oriental_... but I can't find anymore. Please help!

- Thanks. :)

So I'm going to enter an art competition soon and my style is Pop Art. Soooo...I'm stuck between piainting the guys of Franz Ferdinand or Elly Jackson of La Roux.

What do you think?
