Please help Over the years, the thermite reaction has been used to ignite solid fuel rocket motors. Fe2O3 (s) + 2Al(s)
2Fe() +
Al2O3 (s)
The reaction of 0.3150_mol of Iron (III) Oxide with 16.89 g of solid Aluminum produces 0.05412 lb of
Fe. Find the limiting reactant, theoretical yield (in g), and percent yield.
(14 pts)
(Fe = 55.845 g/mol Al = 26.9815 g/mol 0 = 15.9994 g/mol) (1 lb = 453.59 g)

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
