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...
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...
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...
Hi,
I needed some help with my Calculus homework. The teacher gave our class some problems which i have no idea how to start. If someone can tell me how to start the questions or how to approach at solving it... it'll be greatly appreciated. Though I gave my some thoughts. let me know if I am...
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...
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?
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 ?
Hi Gokul,
Thanks for your help. I got q1 & q2...but I am still lost with q3 because even knowing the i factor and equation, i don't know how to determine which compound it is...
(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. ?
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...
Hello,
I needed some help with my Chemistry Homework. I have 4 questions that I'm not so sure of the answer. I've given my best try. Please if someone can help me correct my answers or tell me which one is the right one and how to determine/solve it... Thanks in advance.
Question One...
Hi,
I need some help with my homework. I have three questions which I'm not quite sure which answer it is, though I give it my best try. If anyone can help, it'll be much appreciated. Thanks in advance...
Question One:
Which of the following substances will have hydrogen bonds between...
