Answer:
Right arrow: used to separate the reactants from the products - it is pronounced "yields" or "produces" when the equation is read
Up arrow: an alternative way of representing a substance in a gaseous state
Down arrow: an alternative way of representing a substance in a solid state
So basically,
A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). The two are separated by an arrow symbol (“→” usually read aloud as “yields”). Each individual substance's chemical formula is separated from others by a plus sign. :))
