Should I switch into engineering?

O.k currently I’m taking a Bachleor of Arts degree in international affairs and Culture.I really want to help the world.I’m also very good at these social science courses and have A’s and scholarships becuase of my skills in this field,but I really feel that international relations may not be the way to go to try and help the world.Employment with a B.A is guarenteed only if you want to be a secretary.Politics and words are bullshit.I feel that if you really want to make a difference YOU must create it.
In enginnering I would love to be a mechanical engineer so that I could create environmentally friendly power sources.The poorest countries are rich in eco energry,lots of sun and wind.But I suck at science!my chemistry 30 highschool mark was a 65% and that is me doing it again!I love technology and the potential for good it has,but I will fail engineering,and be bottom of my class.Should I stay in what I’m good at and have no job,or go into something I believe in and fail?

Standard Free energy?

Calculate standard free energy of formation of 1 mol FeS2 at 25 degree’s C

Fe(s) + 2S(s) FeS2(s)

For Fe at 25 degrees C, Delta S = 27.3 J/mol x K
For S at 25 degrees C, Delta S= 31.8 J/mol x K

for FeS2 at 25 degrees
delta S=52.9 J/mol x K and delta H= -178.2 kJ/mol

a–1.9 × 105 J/mol
b–1.8 × 105 J/mol
c–38 J/mol
d–1.7 × 105 J/mol

I saw an ad for a solar powered air conditioner that hangs on the car window.?

It’s solar powered. It will keep the car at around 75 degrees on a 95 degree day. I seen it advertised a couple of weeks ago and didn’t have a pen to write the number to call down. It reminds me of a speaker from a drive-in movie.

Fresnel Lens Focal Length Change with Water, Concentrated Solar Power

This is a raw unedited video in realtime demonstrating the physics of light through a Huger Fresnel Lens. As water is added to the Fresnel side of the lens, the Focal Length triples due to water filling in the grooves of the lens. The optical quality is reduced causing the light to spread over a larger area. The overall energy concentrated is the same (less water filtering). This solar Fresnel Lens with a 40″ focal length increased to almost 9 feet or 108″
