I think it has to be with very strong bonds between C and the halogens. The halogens are pulling very much on the electrons, which makes the molecule very polar, and the bonds very strong. But if someone else could confirm, and go a little more in-depth, you'd probably be better off. What's the...

Ohh, yeah, too fast in the turns!2. is supposed to be 1.75M 3. is supposed to be 0,25 Not sure what I was doing, lol

We have 10mL 1M HCl. 1. add 30mL 1M HCl to original solution: won't affect concentration of HCl. 2. add 30mL 2M HCl to original solution: will affect concentration of HCl to 1,333M 3. add 30mL pure water to original sollution: will reduce [HCl] to 0,04M If one tablet will saturate 5mL water...

The double bond is one sigma bond and one pi bond. Only p orbitals can form pi bonds. P in phosphate still have 10 electrons, 8 of which are involved in sigma bonds, two of which involved in the pi bond. If P is sp3 hybridized, then how do we explain that there are 10 electrons around P...

My query is concerning the hybridization of P in Phosphate (PO43-) I'd like to draw the Lewis dot structure here, but I'm not sure if that's possible. So I drew up some things on my whiteboard, and took a few pictures, there's all the info you need. Look at the left image first, thank you...

So if I were to calculate the mentioned integral, int y, and then find dy/dx, I could just use the fundamental theorem of Calculus and say that if the function is continuous, which it is in the defined interval, and that since y(t)=Y(t), Y'(t)= y(t).. hmm, that was badly formulated, but I hope...

I own both the eleventh and twelfth editions, and I think it's a great book so far. I'm using it in my Calculus 1 course at the uni, first year.

Let's say one has a function y=sqrt(5+(cos(x)^5), and that one must find the integral: lower limit=2 and upper limit=7x2. Is this function defined on a closed interval [2,7x2], or is this function in fact not defined at all, as 7x2 isn't a specific limit? -Compaq

I wasn't aware of any Simpson's method. I'm in Calculus 1, the first course in my first year at uni. I'm not really good - yet:) The main difference so far from high school is arguing to prove a certain rule, the differential rules, for example. I just don't need to know how to use them, I must...

I'm sorry, I forgot to add something crucial into the first post. The whole task is: y=∫√(2+cos3(t)) dt upper limit: 7x2 lower limit: 2 find dy/dx Now, I do not think I can use Calculus's fundamental theorem, and just say that if y=F(x) then F'(x)=y. The function isn't really defined...

Homework Statement ∫√(2+cos3(t)) dtI should perhaps have tried to get the lower and upper limits of this integral (it's defined), but all I'm wondering about is how to calculate the integral. I don't need the answer, but if someone could just point me in the right direction. I've tried...

ahh, so we divide by 2 for the 1s, and then divide by 2 again for the 2s. That gives 180:D Not really logic to me:S Probability is a weird branch of maths. And thanks for the help! Appriciated it.

So I'm going to order a set of 6 digits. There are 4 different digits, but two 2s and two 1s. 6 digits total. The order of the 2s and the 1s doesn't matter. My first guess was 6P4, but that can't be right.

Doing some "how many combinations" calculation Homework Statement We're given the number 123215. How many different numbers can we get by changing the order of the digits? This is a six-digit number, so there are six positions for each digit. This is an unsorted selection with...

Yes, thanks, but what do you call the entire form?
