Durante la fabricación del ácido sulfúrico, el dióxido de azufre (SO2) se hace reaccionar con oxígeno (O2) para obtener trióxido de azufre (SO3), también gas.
a) Escribe y ajusta la reacción que tiene lugar.
b) ¿Cuántos gramos de oxígeno hacen falta para reaccionar con 16 g de SO2?
c) ¿Cuántos gramos de SO3 se obtendrán en ese caso?

Answer(b) 60 miles per hour;

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
