hmmm... what kind of math is it?

I think I have to use "peur" instead of "craindre" though because the way it is use in the text? I was looking back and it says "peur" must be used with the subjontif. So, is "J'ai peur que je ne trouve pas un travail" incorrect? Should "emploi" be used?...

Hi lol Is this correct?: Kp = PPCl5/(PPCl3)(PCl2) = 217.0 torr/(13.2 torr)(13.2 torr) = 1.245 x/(263 torr - x) = 1.245 x = 327.435 - 1.245x 2.245x = 327.435 x = 145.85 torr = PPCl5 263.0 total torr - 145.85 PCl5 torr = 117.15 torr - 13.2 torr = 103.95 tor...

Hi Dr. Bob. I'm coming up with outrageous numbers for when I try to use atm's with my Kp value.. please look! Kp = PPCl5/PPCl3PCl2 = (0.2855)/(0.01737)(0.01737) = 946.3 PCl3 : 0.01737-946.3 = -946.28 atm?! Cl2 : 0.04316 - 946.3 = -946.26 atm o.o PCl5 : 0....

here:) boy's flag pole's height: 5ft 15ft shadow length: x 8ft so you would just multiply 8 ft x 5 ft=40 then divide by 15 feet and get 2.6666 (repeating) so you could just round or whatever but then that would be your answer!

You don't need the information regarding the wavelengths. Step 1: Use Snell's law twice (once on each of the two rays) to find the angle each is refracting at. I'll call the first ray A and the second ray B. Snell's Law: n1*sin(theta1) = n2*sin(theta2) Fi...
