Ksp for Ca(OH)2 is 5.02 x 10^-8. The way to predict whether a precipitation will occur is to calculate Qsp and compare to Ksp. Qsp = (Ca2+)(OH-)^2. Concentration of OH- will be given by (M1V1/V2) = 0.0012 Qsp = 0.850 * (.0012)^2 = 1.22*10^-6 My homework says this is not ...

Yes, both ways are the same. The way the other person told you is in what is called y-intercept form, and the form that you have it in right now (4x - y = 7, I think it was) is called standard form. Basically, just by adding and subtracting things to move them around, you can ...

Yep! They are all solutions! Good job! :-)
*February 17, 2009*

**math**

All you have to do is try out some numbers. An easy way is to place 0 in for x and y to find some easy x and y-intercept points. Just plug in 0 for x. 4 times 0 is obviously 0, so 0 minus what equals 7? 7. Do the same for y. Hope I helped! :-)
