I need help on doing a powerpoint presentation about trichomoniasis

Chemistry
I am stuck on this question: what mass of KCl in grams when 2.00 lbs KC10 3 is decomposed?

You have a mass of 71 kg and are on a 51-degree slope hanging on to a cord with a breaking strength of 165 newtons. What must be the coefficient of static friction to 2 decimal places between you and the surface for you to be saved from the fire? In the previous problem if the...

A skier traveling at 30.9 m/s encounters a 21.5 degree slope. If you could ignore friction, to the nearest meter, how far up the hill does he go?

Physics
I'm still a little confused. When I use the equation: W = k(x2^2 - x1^2)/2, I get 0.0216 J. This doesn't seem correct.

Physics
A spring with k = 54 N/cm is initially stretched 1 cm from its equilibrium length. (a) How much more energy is needed to further stretch the spring to 2 cm beyond its equilibrium length? (b) From this new position, how much energy is needed to compress the spring to 2 cm short...
