multiply 1/6 by 6, you should get 1.
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
I haven't learned how to find a function. Do you mind walking me through it?
This is a PSY230 question for a large grade. I think doing your own homework is better. If you need help with the definitions then go to your online book page 17-19 and this will help on how to do this work.
do your own work!!!
I got a "f" after reading what you had and questioning myself! Thank you!
nope I'll repost it
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
Yes, Chopsticks, after trying the way I described in my last response, I got the same answers you have. Thank you for your help! :-)
Yep! They are all solutions! Good job! :-)
Wow... 1/2 of a ball. :-) I see what you were trying to get across... but our teacher never showed us a problem like this... so frustrating. I don't know if your ratio way is exactly right, but it is a good way to straighten out the info. Wait... I got
Sorry... I tried my best to explain it. Did you look back at my other explanation to the first time you asked it? That might help. It's basically the way our teacher showed us.
Okay... I think the thing we need to do is find another equation then try the elimination method. But what would be another equation? Hmm... :-) Would it (possibly) be a - 15 = b, because 15 mins later, it was (b) minutes after three o'clock?
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! :-)
Mel, I told you already-- 120 and 121. How much they weigh together would be one number-- 141, I guess. I actually don't know how you would figure that part out, but the second part is correct.
Oh, okay. Do you understand now?
Hey Melanii (nooni)! :-) It's me! Anyway, I figured this one out. Well, drwls actually did tell you what you were looking for... their weights. Tweedledee will weigh 121 pounds and Tweedledum will weigh 120 pounds. Here are the two equations as our teacher
i solved for lnx=4,852,725 whats next? and i relaly cant put it into the calc. it says (overflow)
wow, thank you. when do you use the equation -qhot=qcold? I don't really understand fully q3 and q4 for q3 why do u have to use 24g ice but u use the Cp of water and not ice. and for q4 and we used another water equation... why do we have to do this twice?
I meant what would "b" be then? Whoops
What would be be then?
Thank you so much whoever posted all of this info. I am doing an assignment that is due tomorrow for UOP and I could not find anything online to really answer this question clearly for me.
