What are the differences between the graphs Uniform Rectilinear Motion (URM) and Uniformly Accelerated Rectilinear Motion (UARM)?
The URM speed graph will always be constant, so it will simply be a straight line. The UARM speed graph will increase over time, and it will curve.

In a blast furnace, iron (III) oxide reacts with carbon monoxide; the iron ore is reduced and forms metallic iron according to the following reaction. Apply Le Châtelier's principle to determine the direction of the net reaction when a mixture in equilibrium is perturbed and CO is removed:
Fe2O3(s) + 3CO(g) ↔ 2Fe(l) + 3CO2(g)
Indirect reaction (from left to right).

Why does sound exist?
Sound exists because there is a medium through which it can propagate. In this case, on Earth, the elastic medium is air. Sound is produced through vibrations, and these travel through the air. This means that sound does not exist in a vacuum, since there is no way for it to propagate. It is worth noting that sound does not exist in space.
