Imagine you have a light bulb and battery conductivity tester. You are given a dilute of copper sulfate and a dilute solution of vinegar, acetic acid. Copper sulfate is an ionic compound. You may recall that acetic acid reacts with water to produce ions in solution according to the equation below: H2O + CH3COOH <--> CH3COO- + H2O+
a.What would be the result if you tested each of these solutions for conductivity?
b.Suppose you added more copper sulfate and acetic acid to the solutions and retested. Would that change the results? Explain your answer.
c.If you continued to add copper sulfate and acetic acid until the solutions held as much solute as possible what would be the result? Explain your answer.

I'm preparing for my final examination. However, I did not come to class some day, I could not understand some problems.
---------------------
Caculate the derivatives:
d/dt intergal[from 1 to sin(t)]Cos(s^2)dx

d/dt intergal[from e^t to t^3] spr(1+x^2)dx
---------------------
The answer for (1) is Cos(Sin(t^2)(Cos(s))

I read that you should fill your vehicle's fuel tank up on colder days as opposed to warmer days b/c on colder days the density of the gasoline is higher thus u get more gasoline (mass) per volume (gallons). That seems reasonable but how much of a difference would it really make? (eg how much more dense is it say at 10 deg. F as opposed to 60 deg F.) I tried to research this a bit and now I am also wondering what the difference is between 'winter grade' gasoline and 'summer grade' gasoline??

Hi can someone give me some advise. I am currently taking my AS in clinical medical assistant. And I have been doing some volunteer work at my docotors clinic since I was a junior in HS. Like in my junior yr I did 2 mo's of volunteer and in my senior year I did about 2-3 mo's. And I am planning on going to a comm. college to start taking classes to prepare me for medical school.
I wanted to know exactly what type of volunteer work do medical schools look at when it comes to applying for addmission?? Like for the volunteer section I have experience in filing papers and being a receptionist helper.
And I am gonna be SOON doing clinical volunteering as a clinical medical assistant. Would my volunteer experience help me get into medical school along w/ the prep classes and test's I'm gonna be taking?? Should I volunteer at a hospital too?
Would it matter when it comes to applying to medical school like if they see that I had taken a 2 yr degree before going onto a 4 year degree

i know no one can even get close to it cause it's scorching hot, but if there could be a space suit that can be worn that would not burn anyone (just pretend for a minute here), can the astronaut step on LAND on the sun or is it just hidrogen and helium and other such particles but it's not like land where you can step on it?

Why do all modern biologists reject lamarck's theory of evolution?

they use so much fuel and it seems wasteful to me. it would be a lot easier if they took off at a similar angle than airplanes. then just get insane altitude and leave the atmosphere. just seems like they wouldn't have to use like 1000 gallons per second during take off and launch. i don't know. why don't we just make flying saucers lol.
