According to this graph, which statement describes how the amount of iron changes over time in the reaction
fe2o3 + 3h2 → 2fe + 3h2o?
a.
the amount of the product fe increases rapidly at first and then continues to increase slowly.
b.
as time passes there is steady decrease in the amount of fe.
c.
as time passes fe2o3 and fe will reach a dynamic equilibrium.
d.
the amount of the reactant fe2o3 increases rapidly at first and then continues to increase slowly.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
