Chemistry genius needed!!?
The combustion of octane is as follows: 2C8H18 + 25O2 => 16CO2 + 18H2O Since you've got 700 grams of octane, you can figure out how many moles you've got (12.01*8 + 1.01*18 = 114.26 g/mol, or 6.13 mol octane) Do the math: 6.13 mol octane * ( 16 mol CO2 / 2 mol Octane) * (35.01 g / 1 mol CO2) = 2156.975 g CO2 formed. For the % yeild, take the given and put it over the calculated, the answer is 88%
For Geniuses Only......I Need Help!?
A 1.65 kg rock is released from rest at the surface of a pond 1.00 m deep. As the rock falls, a constant upward force of 3.90 N is exerted on it by water resistance. Calculate the nonconservative work, Wnc, done by water resistance on the rock, the gravitational potential energy of the system, U, the kinetic energy of the rock, K, and the total mechanical energy of the system, E, for the following depths below the water's surface. Let y = 0 be at the bottom of the pond. If d=0.50m find the: (a) Wnc done by water resistance on the rock. (b) gravitational potential energy of the system (c) kinetic energy of the rock I've been trying this problem for an hour now. Can someone please show me how to do it. Thanks for your time!!
CHEMISTRY GENIUS NEEDED!!!10 POlNTS FOR BEST ANSWER!?
Equations like this are trial and error, or the algebraic method. Combustion of carbohydrates have " strategies. "
How can a genius know the answer if they did not go to school and learn those basic facts or gain knowledge about the topics?
OK. You’re looking at this backwards.Intelligence is what you use when you don’t have knowledge to go on. If you have knowledge there is no need at all for intelligence - you already know the answer. The dead tree version of the Encyclopaedia Britannica has a lot of knowledge stored in it but can’t actually add to it.Intelligence is much more about fitting the knowledge you do have together in interesting ways and working out what the right question is to ask to tap the knowledge you have and have access to. (This actually does tend to increase the amount of knowledge you have because it’s easier to learn things as part of a framework than as discrete meaningless facts).And thinking about the Answer is also looking at things the wrong way. The trick is in knowing what question to ask. In looking at something and asking why it can’t be improved.Finally if you read the biography of any genius and they are being honest it will show they failed and came up with bad ideas lots of the time. Because they kept asking questions, kept trying to fit things together, and a lot of the time when they were starting out the questions were only slightly more sophisticated than “What would happen if we made the wheels square?” But they learned the answer and kept asking even when the early questions proved to be bad ones. What people remember and care about isn’t the twenty bad questions that the answers were simple to. It’s the one good one where people hadn’t asked it before. Whereas if they’d asked no questions they wouldn’t have found the good one.
Really hard question only a math genius could answer?
from hereon lower-case letters denote individuals (representing 1 boy/girl) and upper-cases / capitals represent groups (1 or more boys/girls, ). and i'll use "." as mps. 1 mp = 2 arrangement (arr) boys and girls in their flock. B.G and G.B (bbbbggg and gggbbbb) 2 meeting points (mp) = 5 arr boys in group, divide girls into 2 (2 ways) AND girls in group, divide boys into 2 (3 ways). B.G.B (3*1=3) and G.B.G (2*1=2) 3 mp = 6+6 = 12 arr both are divided into 2. B.G.B.G (3*2=6) and G.B.G.B (also 2*3=6) 4 mp = 6+3 = 9 arr 3 vs 2 groups. B.G.B.G.B (3*2=6) and G.B.G.B.G (1*3=3) 5 mp = 3+3 = 6 arr 3 vs 3 groups. B.g.B.g.B.g (3*1=3) and g.B.g.B.g.B (1*3=3) 6 mp = 1 arr 4 vs 3 groups. b.g.b.g.b.g.b (1*1=1) average = [sum of (mps)*(respective # of arr)] / [sum of arr] = [1*2 + 2*5 + 3*12 + 4*9 + 5*6 + 6*1] / (2+5+12+9+6+1) = [2+10+36+36+30+6] / (35) = 120 / 35 = 24/7
Math genius needed! Stuck on a question!?
First you have to convince yourself, by drawing or whatever, that reflecting a point (p,q) in y = -x results in (-q,-p) i.e. swap the x and y coordinates and toggle their signs. Once you know this, it is trivial to reflect 3x - 5y + 7 = 0; just replace x with -y and y with -x i.e. 3(-y) - 5(-x) + 7 = 0 => 5x - 3y + 7 = 0.
Another ultra difficult math problem only a genius could answer?
since your given energy = inversely proporational to wavelength, let E = energy k = proportionality constant λ= wavelength therefore, again, given E is inversely proportional to λ..... E = k x 1/λ next.... let E1, and λ1 = energy and wavelength of red photon E2 and λ2 = energy and wavelength of other photon k is the same constant for both photons.... so..... E1 = k x 1/λ1 and E2 = k x 1/λ2 next rearrange both equations..... E1 = k x 1/λ1 ------> E1λ1 = k and E2 = k x 1/λ2 ------> E2λ2 = k but since both "k's" are equal..... E1λ1 = E2λ2 or E1λ1 / E2 = λ2 or (E1/E2) x λ1 = λ2 now we know that E2 = 2000 x E1 right? substituting into above equation gives.... (E1/E2) x λ1 = λ2 -----> (E1/(2000x E1)) x λ1 = λ2 λ2 = (1/2000) x (7 x 10^-7 m) = .0035 x 10^-7 m = 3.5 x 10^-10 m (fyi that's in the x-ray region of the em) ********** hey Roger ************ it's 10^-10 m not 10^-8 m you work for the government eh? :) and you are or are not crazy?
Do you need to be a genius to be admitted to Caltech or M.I.T?
California Institute of Technology is very selective (11% of applicants get in) and applicants score really high on Math in both SAT (770 to 800) and ACT (34-36) tests.Massachusetts Institute of Technology is even more selective (8% get in, and they get more applications too) and the tests scores are similar.Those are the facts. That being said, the definition of genius is becoming more and more blurried every day. We live in an era of informational availability such that curiosity and determination alone will take you very far. And it turns out many of these great schools look for those qualities just as much as for great test scores and grades. Don't be discouraged. Check out Lea Verou's story, who studied in Greece, then started a career as a freelancer web developer, and then got admitted into MIT to do her PhD. http://lea.verou.me/2014/02/im-g... Bottom line is, no matter whether you consider yourself a genius or not, Dream Big my friend!
Do I need to be genius to think of a brilliant startup idea?
No ... A big NO..."Sometimes it is the people who no one imagine anything of who do the things that no one could imagine"- Alan Turing (Father of computer science)Think of every startup on the earth ... Every startup is born as an idea in someone's mind.. So you only need to be a mere observer not a genius...A startup is created to solve a problem that the founder or his friends or relatives suffering from.. Take the example of Facebook ,When mark zuckerberg created facebook , only because he has to recreate a good image after the big problems developed due to his facemash.Apple was started only because of a mere idea of computers that steve jobs got by seeing the plug and play electronics circuit created by steve wozniak..There are lot more examples also...So if you want to get an idea , you don't need to be a genius an also you don't go behind just ideas .. go behind the problems that you can solve with a business intension in the mind..Also you should have passion in what you are doing..All the best manh!!! Do well!!!
