Question

What will be the electronic configuration for the complex K3[Fe(oxalate)3].3H2O? t2g4 eg1 t2g3 eg2 t2g2 eg3 t2g5 eg0

Answer 1

Answer:

Balanced equation: 3Fe + 4H2O → Fe3O4 + 4H2

Step 1: Write the unbalanced equation

Fe + H2O → Fe3O4 + H2

Step 2: Compare the number of atoms of reactants with the number of atoms of products.

Step 3: Now, first we consider the element having unequal no. of atoms on both sides. Thus, first let us consider Fe atom. If we multiply 3 in the reactant (in Fe), we will get the equal number of atoms as in product (in Fe3O4)

Step 4: Write the resulting equation:

3Fe + H2O → Fe3O4 + H2

Step 5: Now check whether the equation is balanced or not by comparing the atoms

We find that the equation is not balanced yet. As the number of oxygen atoms is unequal on the two sides. Hence, balance the oxygen atom.

Step 6: If we multiply 4 in the reactant (in H2O), we will get the equal number of oxygen atoms on both sides.

Step 7: Write the resulting equation:

3Fe + 4H2O → Fe3O4 + H2

Step 8: Now check whether the equation is balanced or not by comparing the atoms.

We find that the equation is not balanced yet. As the number of hydrogen atoms is unequal on the two sides.

Step 9: Now, we consider hydrogen atoms. If we multiply 2 in the product (in H2), we will get the equal number of hydrogen atoms as in reactants.

Step 10: Write the resulting equation:

3Fe + 4H2O → Fe3O4 + 2H2

We find that the equation is balanced now.

Step 11: Write down the final balanced equation:

3Fe + 4H2O → Fe3O4 + 2H2
