    Organic Chemistry - Nomenclature Structures

    The question/direction is to: "Draw the structure of the following compound!" 2-methyl-4-(1-methylethyl)octane I tired several different ways of constructing this compound but the online homework program ACE Organic says that: I don't know what to do or what I am missing. If anyone can...

    How Do You Solve Challenging Calculus Homework Problems?

    Ok so using the volume formula of a cylinder, I found the rate of the radius decreasing as dr/dt = 39.78 V = (pie)(r^2)(h) dv/dt' = (pie)(2r)(dr/dt)(dh/dt) **dv/dt is 10'' per second ** dh/dt is 0.02'' thickness Please let me know if this is how this problem is supposed to be done or...

    How Do You Solve Challenging Calculus Homework Problems?

    Hey, yeah sorry its suppose to by Y=ax^3 + bx^2 + cx + d I editted the first post now. thanks for letting me know. And now that i see the picture, I think yea sphere isn't good formula. maybe a cylinder V=(pie)(r^2)(h) ? The thickness can be plugged in for the height, i suppose? and r is...

    Chem II - Solubility & Boiling Pts.

    oh ok. i understand it now. We need the final T so we have to subtract 100 from 101.4. and the use the equation and solve for the Ions which is 2 (KCl) Thanks for your help with this. It's been very confusing with gases and these equations. I'm glad someone here was to help me. I also...

    Chem II - Solubility & Boiling Pts.

    ok so when i do that division i get 2.04 =2 Ions ? but where do u get 1.4 from? and still what does that division 2.04 result mean? I am guessing the answer should be (D) KCl since it has 2 elemnts/ions?

    Chem II - Solubility & Boiling Pts.

    Hi, I used the equation (delta)Tf = i(Kbm) and solved for i which I got as 1.021... How do I calculate the i-factors for the compounds when I have no other information? Would I be looking at the number of Ions or moles ?

    Chem II - Solubility & Boiling Pts.

    (c) would also be considered Hydrogen Bonds since it has F attached to the H. Hydrogen Bonds include N, O, F - Not sure why they are Ion-dipole forces but I'll look it up. q2: so then it would be (d) since it has more Ions. ?

    Chem II - Solubility & Boiling Pts.

    Hey thanks for your quick help. No actually these arent from chem book. The teacher either writes them up or gets from other websites...not sure. So for question one: since H2O is a hydrogen bond force, letter (c) HF would be more soluble, since that is also a hydrogen bond ? q2: I...
