Chemistry
I'm having a hard time balancing the following chemical equations: - F2 + NaOH -> O2 + NaF + H2O - Ca(AlO2)2 + HCl -> AlCL3 + CaCL2 + H2O - Ba(OH)2 + HNO3 -> BA(NO3)2 + H2O

Physics-repost, sorry, I still don't understand :(
A forearm with a mass of 1.2kg supports a ball with a mass of 5.44 kg. The forearm is 0.050m long; it's perpendicular to the arm is 0.35m long, the center of gravity is at 0.15m from the elbow. Find the force exerted by rhe biceps and the force on the elbow joint. I know t...

So, how can I slove it, please?

Physics - help really needed
can someone pretty please help?

oh, ok, I see; i had thouht of something along those lines, but was thrown off by seeing two variables, but now I see how that can be done; thank you!

Physics
oh sorry, 4 meters apart, I mean.

Physics
Three men 4, apart are carrying a heavy load on a pole. Two are one end of the pole and the third is at the other end. Where should the load be placed so that each man gives equal support?

Someone doing Lenny's Conundrum?! :)
