Yeah it was gallium not germanium, my mistake. So Ga is 3+ and Se is 2- right? So then its Ga2Se3. Because you'd need to balance the charges out by multiplying both by 2 to give 6+ or 6-. Thats still not the answer that was given in the book. Its Ga2Se. I'm not seeing how whats the answer.
I still don't understand the second one. Ge has a charge of 4+ doesn't in? since it is in group 4A? and Then Se has a charge of 2-? So wouldn't the answer be GeSe2 instead of Ge2Se?
I'm also having trouble with this problem:
carbon monoxide gas reacts with hydrogen gas at elevated temperatures to form methanol according to this equation:
When 0.40 mol of CO and .30 mol of H2 are allowed to reach equilibrium in a 1.0 L container, 0.060 mol of CH3COH are formed. What is the value of Kc?
What I did was:
I got Kc to be 1.7. My ACS exam book says that the answer is 5.4 though.
I think I understand number 3. It has to do with the amount of protons in each atom right? They all have the same amount of electrons so more protons will pull harder on the electrons, making the atom smaller. correct? I still don't understand questions 1 and 2 at all.
I don't drive.
Fuck da po-lice.
I'm looking to get back into PC gaming so I dusted off my old build from 2009. As of right now, my video card is severely outdated and my heatsink is barely hanging on because the little push pins are broken. Its the stock heatsink. So, I need to replace some parts.
Now, if the i7 920 is still a pretty decent processor, I would like to keep that and overclock it to save some bucks, but I'll need a new heatsink. I don't have any experience OC'ing but I know you have to have a decent set of RAM to get anywhere, will these 6 GB be good enough to OC to around 3.6GHZ? And is 6GB enough these days for gaming?
I will also need a new HDD, I'm thinking of a SSD, I've been using a 5400 RPM eMachines HDD since like 2003
I've got a pretty broad biology question that I have to write about and I'm having some trouble getting started with it. How can two nearly identical protein sequences (from two different species) code for such huge differences in proteins? If you have any articles or webpages that can help me get started with this question that would be greatly appreciated, as I really have no idea where to start with this.
Hey what are the names of some pigments?
Consider the reaction: A + B → products
The following rate law was experimentally determined: rate = k[A]2
If the concentration of A doubles and B stays the same, the rate will?
What if both A and B are doubled?
Hydrogen chloride decomposes at high temperatures to hydrogen and chlorine gases:
The reaction is second order with respect to [HCl]. BY what factor does the rate increase if the concentration of HCl is tripled?
I know the answer is nine. But i have no idea why. Instinctively, the answer was 6 to me because of the 2 in front of HCl. 2*3=6. But that is not correct. Can someone please explain?
But P varies. Are you allowed to do that even though P is not constant?
I dont know man. Life as a mathematician seems to be pretty boring to me. It is cool to know, but there is no feeling or creativity in it.
What type of DNA mutation can cause either a macro (more than 1 bp changed) or a micro (1 bp changed) lesion?
yea, but doesn't a black hole's mass accumulate, constantly getting more massive from what it sucks in?
also, how was the mass content of the universe measured and compared with the net gravitational force in the universe?
I thought string theory rolled over, died, and was surpassed by m-theory?
Nope, his popularity was never particularly high. Even in early days the Nazis struggled to gain support and never managed to gain a majority in the Reichstag, all of this despite murdering and banning the opposition along with a massive campaign of intimidation against anyone who spoke out against them. I would hazard a guess that even the Lib-Dems would do a better job of gaining support were they able to murder Tory leaders, ban the Labour party and beat the shit out of anyone who said anything bad about them.
In terms of efficiency, that whole thing was a mask. You look at the details of Nazi organization and the Bureaucracy which they set up and it becomes very clear. The way which they were running things was unsustainable; war was not an incidental thing that ruined their success, war was a fundamentally necessary thing that they required in order to allow and then prolong their apparent economic successes. To take a simple example, the reduction in unemployment is often cited as an example of Hitler’s economic success, but it was only possible due to a combination of massive rearmament and removing an entire class of people (Jews) from the workforce. Without the war and genocide that would have collapsed even sooner.
Math isn't really all that important...
OK Pit, I need your help.
Does anyone here currently use Linux, and if yes, can they talk me out of installing Ubuntu (whether in favor of another distribution or just not considering it altogether)? I've been running it via a virtual machine for a while and I think I can work with it nicely. I'm currently studying Information Technology (ie programming / system administration) and am being taught how to do this all on Linux via that same virtual machine.
I should add that I don't give three sh*ts about gaming on the computer I want to run Linux on - I have another computer for that exact purpose.
Graduated today! Whoop! I start my PhD next week. Any other PhD students got any tips or pointers?
So Microsoft have figured out that my windows 7 isn't legit (It is in a way, but i took it from my friends HP Laptop), and they've basically bullied me into submission to purchase windows. My only question is, am i gonna lose everything i have downloaded? Including my game saves (actually doing well in Dayz, don't wanna ruin it ).
I don't need AV software? That's interesting, why is that?
I'm wondering if i can get any help with this vector problem.
I need to know how to find the Y-component of the 100N force. I have the answer which is100cos(45°sin (60°, but i have no idea how to get it. Any help would be much appreciated. Thanks
I need to understand what is inversion symmetry, to start recognizing wether molecules are polar or not.
But as far as I've seen wikipedia and youtube vids, I don't get a ****.
Can someone explain me just how to recognize the symmetry, in some way I can understand it?
Logging in as root is almost always a terrible idea. Sudo is there for a very very good reason. Step number one in any Linux command line tutorial is always "You're a shitty person if you log in as root, don't do it nublet."
Oh, I see what you mean now. At least it's stuff you can re-download.
Don't fear root, embrace it as your friend but always respect it's power.
I find it a bit funny when people are skittish to use root or super-user privileges. I generally let them though because those people are probably the ones that don't know what they're doing and shouldn't be using it.
I've done a sudo rm -rf / a few time to wreck a system just for fun. After a proper backup of course.
edit: just realized my user title is relevant to the conversation.
Root is not evil, root is a large part of what makes Linux brilliant. If you're mentally incapable of using it, then it can be deadly. I often wonder how people do ridiculous things, like do they just read a command, have no idea what it does and then decide to run it? "Hmmm, sudo rm -rf /... Seems legit."
I get inadvertently writing over a file or something like that, but I can't understand running something that just dummies the system without having any idea what it would do.
Having deleted 50GB of downloads, I think it's safe to say I won't automatically trust guides on the internet when they tell me to run things as root...
It can't be both?
To the guy above me.
I admit that I am woefully ignorant to scientific matters. And while that does not justify my belief it simply puts a bigger role for the divine. It's not that I think God programs computers but more along the lines of th possibility for humans o create computers is there because of the world that we occupy. God to me is like the keeper of the natural laws of the universe.
It's not singularly my own thought, don't make this out to be me as the lone hold out. I just feel as though scientific evidence does not explain the universe that makes sense to me. What good (to me) is an explanation that does not make sense to me? It isn't very useful.
What caused the big bang? The big bang occurred because of a collision of particles (am I right on this?) therefore there was a certain rate of speed that these particles must have been moving. rate=distance/time. If we acknowledge that there is an age of the universe then we acknowledge that there is a time now. We can subtract this time until we get to zero, at which point there is no rate of the universe. There must then be an actor that acts upon the universe to set it into motion.
Glad to see how busy this thread is lately.
Okay, so hopefully last calculus question ever...
Find the area of the region that lies under the graph of f(x)= x between x = 0 and x = 2 by taking the limit of the sum of approximating rectangles whose heights are the values of the
function at the right hand end point of each subinterval.
So, I'm not too too bothered with an in depth understanding of how to do this sort of question as I only have to answer one of them for my entire course, but any resources for a step by step on how to solve this? I know basic integrals and stuff, but this sort of question uses a lot of notation that I've never seen, like i's and Sigmas and crazy shit.
