Balance the following in an acidic solution:1]Fe ----> Fe(OH)2 & 2]NO3 -----> NH4^+

To balance a chemical equation in an acidic solution, you need to follow a few steps. Let's balance the given equations one by one:

1) Fe ----> Fe(OH)2

This equation represents the oxidation of Fe to Fe(OH)2. However, the reaction is not balanced yet. To balance it, follow these steps:

Step 1: Write the unbalanced equation:
Fe ----> Fe(OH)2

Step 2: Balance the elements other than hydrogen and oxygen. In this case, we only have iron (Fe), so the iron atom is already balanced.

Step 3: Balance oxygen atoms by adding water (H2O) on the side that needs more oxygen. In this case, the right side (Fe(OH)2) needs one oxygen atom, so let's add one water molecule on the left side:

Fe + H2O ----> Fe(OH)2

Step 4: Balance hydrogen atoms by adding H+ ions on the side that needs more hydrogen. In this case, the left side (Fe + H2O) needs two hydrogen atoms, so let's add two H+ ions on the left side:

Fe + 2H2O ----> Fe(OH)2

Now the equation is balanced in terms of atoms. However, since the reaction occurs in an acidic solution, we need to balance the charges using electrons (e-) as well. To do this, we will add electron(s) to the side that needs more negative charge. In this case, the left side needs an extra negative charge, so we add two electrons:

Fe + 2H2O + 2e- ----> Fe(OH)2

Now the equation is balanced both in terms of atoms and charges, satisfying the conditions for an acidic solution.

2) NO3 -----> NH4+

This equation represents the reduction of NO3 to NH4+. To balance it, follow these steps:

Step 1: Write the unbalanced equation:
NO3 -----> NH4+

Step 2: Balance the elements other than hydrogen and oxygen. In this case, we only have nitrogen (N), so the nitrogen atom is already balanced.

Step 3: Balance oxygen atoms by adding water (H2O) on the side that needs more oxygen. In this case, the left side (NO3) contains three oxygen atoms. To balance this, let's add three water molecules on the right side:

NO3 + 3H2O -----> NH4+

Step 4: Balance hydrogen atoms by adding H+ ions on the side that needs more hydrogen. In this case, the right side (NH4+) contains four hydrogen atoms. To balance this, let's add four H+ ions on the left side:

NO3 + 3H2O + 4H+ -----> NH4+

Now the equation is balanced in terms of atoms. However, since the reaction occurs in an acidic solution, we need to balance the charges using electrons (e-) as well. To do this, we will add electron(s) to the side that needs more negative charge. In this case, the left side needs an extra negative charge, so we add five electrons:

NO3 + 3H2O + 4H+ + 5e- -----> NH4+

Now the equation is balanced both in terms of atoms and charges, satisfying the conditions for an acidic solution.
