A solution is prepared that contains 0.0200 M AgNO# and 0.150 M KSCN. What is the equilibrium concentration of Ag+ ion in this solution? The Kf for Ag(SCN)4^3+ is 1.21x10^10 I'm not even sure how to set up this problem? Would I need to do an ice box? Ag(S...

A student places 0.025 moles of solid sulfur and 0.100 moles of nitrogen monoxide gas in a closed 1.00L container and 0°c for several days. Calculate the number of molecules of NO in the 1.00L container after equilibrium is reached, given the following th...

Calculate the pH of the solution that is prepared by mixing 26.06g of ammonium iodide (MM=144.942) and 5.08g of ammonia (MM=17.034g) in enough 0.066 M HCI to produce 1.00L of solution. Kb(NH3)=1.76x10^-5 I converted 24.06g and 5.08g to moles and i now I h...

I'm not sure how to set this question up... A solution containing 0.015M Sr^2+ and Ba^2+ ions is treated with Na2SO4 and a percipitate containing one metal sulfate forms. Assition of the sulfate ion continues until the more soluble sulfate salt just begin...

Diiodine pentafluoride reacts spectacularly with bromine trifluoride to form iodine pentafluoride, oxygen gas, and liquid bromine. In a particular reaction a 44.00g sample of I2O5 reacts with 58.00g BrF3. What is the mass of the excess reagent? This is wh...

I was told to post at the beginning of the page: not sure if I did so or how to really do it but i'm posting the question again): Diiodine pentafluoride reacts spectacularly with bromine trifluoride to form iodine pentafluoride, oxygen gas, and liquid bro...

The thermodynamic data: s No So2 N2O S 31.9 211 256 220 ∆H 0 90.4 -297 81.6 I solve for ∆G and got an answer of -446287.3 then I used that to find K which is 2.48 x 10^85. I set up the ice box just like you showed but do I set it equal to K? (2x)(X)/0.1-4...

I really suck at Chemistry = [ Thank you for taking the time to explain it to me and answer my many questions! It is very helpful!
