_HNO3+ Fe+2
1 answer:
Answer: The coefficient for water after the equation is balanced is 2.
Explanation:
The balanced chemical equation must have same charge and same number of atoms on both sides of the equation.
As the given reaction is a redox recation occuring in acidic medium.
The coefficient for water will be 2 after the equation is balanced.

Explanation:
(1). It is known that in a reaction equation, reactants are placed or written on left hand side and products are written on the right hand side.
For example,
Hence, in a reaction equation you start with the reactants and end up with the products.
(2). The number of atoms in a reaction will remain the same because according to the law of conservation of mass, mass of reactants will be equal to the mass of products.
Therefore, number of atoms on the reactant side will be equal to the number of atoms on product side.
