1.	{:(AgNO_(3)(aq)+NaCl(aq)toAgCl(s)darr+NaNO_(3)(aq)),(""FeS+H_(2)SO_(4)toFeSO_(4)+H_(2)Suarr):} Consider the above mentioned two chemical equations with two different kinds of arrows (uarr) and (darr) along with products. What do these two different arrows indicate ?
Answer» Solution :The upward ARROW `(uarr)` indicates that the product is a gas while the DOWNWARD arrow `(uarr)` indicates that the product is insoluble and appears as precipitate.
