Write the skeletal equation for the following reactions: (i)Hydrogen

1.	Write the skeletal equation for the following reactions: (i)Hydrogen sulphide reacts with sulphur dioxide to from sulphur and water. (ii) Methana on burning combines with oxygen toproduce carbon dioxide and water . What is the need of balance equations ?
Answer» Solution :(i) `4H_(2)S+2SO_(2)rarr6S+4H_(2)O` (ii) `CH_(4)+2O_(2)rarrCO_(2)+2HO` To obey the law of CONSERVATION of mass, so that the NUMBER of atoms of each element before and afterthe reaction remain the same.
