Homework Statement Using the activity series table, explain how we can separate the following metals from the corresponding salts 1. AgNO3 2.PbCl2 3.ZnCl2 4. AlCl3 This is for my chem 1 class. I'm terrible in this class and I desperately need help solving this.

Villanova is an hour and a half west of Rutgers. Weather should not be that much different...

I've been accepted to UMICH, Rutgers, Penn State, Villanova, and Drexel engineering. I've narrowed down my college choices down to the ones I can afford, Villanova and Rutgers. I'm visiting both next week. Both will also cost the same. I plan on majoring in mechanical/aerospace engineering...

Alright thanks. WE haven't learned integration yet do I couldn't do it your way

So the object is moving forward s(1)=t2+tlnt s(1)=1 s(e)=e2+elne s(e)=10.1017 10.107-1=9.107 it goes 9.107 units foward??

So the answer for part d would be that the object accelerates between [1,e] but does not decelerate?can you show me how to do part c, I have no idea how to do that part

2t+1+lnt>0 and 2t+1+lnt<0 Howw would you even solve that inequality? 2+(1/t)>0 1/t>-2 -1/2<t So its accelerating at t>-1/2 and declerating at t<-1/2? Would I even write when that since those numbers arent in the domain [1,e]?

The function s(t)=t2+tlnt gives the position from time [1,e] find: a. the velocity at time t b. the acceleration at time t c. describe the motion of the object: when is it moving forward or moving backward. also compute the total distance traveled during the interval d. when is the object...

The problem is: For the baseball diamond in exercise 33, suppose the player is running from first to second at a speed of 28 feet per second. Find the rate at which the distance from home plate is changing when the player is 30 feet from second base. (the picture basically shows a square with 90...

Alright thanks guys! So for example if it said f '(3) I would only use the x values at 3 which are [2,1,3,-1]?

Is this work right?...

Thanks I really appreciate your help. It really is an interesting topic that you brought up. But would that really qualify as a "small engineering project?" I picture what you brought up as being something complex that could cost a lot of money

I'm currently working on my UVA application and finished it all except for one part. Its a small writing portion of about 250 words. It states: "If you were given funding for a small engineering project, what would you do?" I chose Biomedical Engineering as my major. So perhaps relating my...
