Y and Z are metals known to undergo the following reactions at high temperature.
2YO > 2Y + O 2
2ZO > 2Z + O 2
Bishen, Chandra, Prasanna and Venkat are looking at the following written on a piece of paper and wondering if it is a valid chemical equation.
YO + ZO > Y + Z + O 2
Bishen : It is valid because it is balanced.
Chandra : It is valid because YO gets reduced to the metal Y and ZO gets reduced to the metal Z as per the above two equations.
Prasanna : It is efficient because it avoids the trouble of writing two equations separately and the law of conservation of mass is not violated. It's just like adding 2 algebraic equations.
Venkat :This equation can lead to a wrong understanding that YO and ZO can be reduced ONLY if they are reduced together.
Who understands chemical equations best?
