Homework Statement Suppose that 3 is < and equal than f'(x) which is also < and equal to 5 for all vales of x. Show that 18< or equal to f(8) -f(2) < or equal to 30. Homework Equations Mean Value theorem The Attempt at a Solution I have no clue where to start or which values...

Homework Statement A metal fluoride crystallizes in a cubic structure such that the fluoride ions occupy lattice positions at the corners and on the faces while 4 metal atoms occupy positions within the body of the unit cells. The formula of the metal fluoride is? I don't know where...

I was just wondering how you might use Lewis theory to predict the reaction of molecules with an incomplete octet with a molecule that contains a lone pair? The idea is very abstract to me, I'd appreciate any ideas.

yikes I should probably work on my recopying skills. thank you very much!

thank you very much that makes so much more sense

Chain rule difficulties, due tomorrow! Homework Statement Find the derivative of y=e^square root of 1+tan(sinx) Homework Equations chain rule: F'(x)=f'(g(x)) * g'(x)The Attempt at a Solution I thought I had it and then while I was looking at other chain rules and started doubting my...

I was reading about the photoelectric effect and it described that in the classical description of light, the changing of wavelength would effect the rate at which electrons were emitted. This theory was later proved wrong when Einstein introduced the idea of photons. However this theory goes on...

Homework Statement Suppose 1.00g of Mn Reacts with an excess of 6.00M HCl, how many grams of H2 gas is produced? What volume hydrogen gas is produced by this reaction? Homework Equations density of hydrogen gas is 0.08988g/L conditions: 0 degrees celsius, 1 atm pressure The...

maybe P1V1/T1 = P2V2/T2 ? Sorry I used to know this but i can't seem to remember

I am trying to find % acetic acid by volume in vinegar. I have 8*10-4 mol/L of acetic acid in vinegar and 8*10-5 of acetic acid in the dilute sample of vinegar and water. I know that the volume/volume % is equal to the amounts of A divided by the total amounts of A and B. BUT that...

I'm having a little bit of an issue trying to find an equation to use when the initial and final temperature, pressure and volume are all variable I know \frac{V1}{T1} =\frac{V2}{T2} and \frac{P1}{T1} =\frac{P2}{T2} and P1V1=P2V2 But I want to combine them so that I can get the V2 when the...

The question asks to find a value for a and b that makes f continuous everywhere. f(x)= \frac{x - 4}{x-2} , where x<2 ax2 - bx + 3 , where 2<x<3 2x - a +b , where x > or = 3 I know that in order for a function to be continuous the limit as x approaches 2 must be equal from...

Yes! that definitely got my wheels turning, I ended up rationalizing it by the multiplying of both the top and the bottom of the equation with the opposite of the numerator and an answer of one half. Thanks for the help again

thank you so much both of you, I really had no idea what I could branch out of the equation and I would never have found that on my own

The question is as follows: \frac{lim}{h\rightarrow0} \frac{\sqrt{1+h}-1}{h} I don't know if the way I approached the question is right, I'll give you a step by step of what I attempted: First I converted the square root into 11/2 and h1/2 (can I do that? Is that correct?) Then I...
