9. En la combustión del propanol (C3H8O) se obtiene dióxido de carbono y agua. A) Escribe y ajusta la ecuación del proceso. B) ¿Cuántos moles de oxígeno se necesitan para producir 1,3 moles de dióxido de carbono? C) Con 120 g de propanol, ¿cuántos moles de agua se obtendrán?, ¿qué masa tienen?

12000j is work done

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
