Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation one by one.

1. AgNO3 + Zn -> Zn(NO3)2 + ?Fe

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides. Let's start with the zinc (Zn) atoms:

On the left side, we have 1 Zn atom, and on the right side, we have 1 Zn atom in Zn(NO3)2. So, the coefficient for Zn is already balanced.

Next, let's balance the nitrogen (N) atoms:

On the left side, we have 1 N atom in AgNO3, and on the right side, we have 2 N atoms in Zn(NO3)2. To balance the N atoms, we need to put a coefficient of 2 in front of AgNO3.

The balanced equation is: 2AgNO3 + Zn -> Zn(NO3)2 + ?Fe [[1]].

2. ?Fe + ? -> FeCl2

Since the equation is incomplete, we cannot balance it without knowing the reactant and product. Could you please provide the missing reactant and product?

3. FeCl2 + ? -> FeCl3

Similar to the previous equation, we need the missing reactant to balance the equation. Could you please provide the missing reactant?

4. K2S + CuCl2 -> KCl + ?

To balance this equation, let's start with the potassium (K) atoms:

On the left side, we have 2 K atoms in K2S, and on the right side, we have 1 K atom in KCl. To balance the K atoms, we need to put a coefficient of 2 in front of KCl.

Next, let's balance the chlorine (Cl) atoms:

On the left side, we have 2 Cl atoms in CuCl2, and on the right side, we have 1 Cl atom in KCl. To balance the Cl atoms, we need to put a coefficient of 2 in front of CuCl2.

The balanced equation is: K2S + 2CuCl2 -> 2KCl + ? [[2]].

5. Na2O + H2PO4 -> Na2PO4 + ?

To balance this equation, let's start with the sodium (Na) atoms:

On the left side, we have 2 Na atoms in Na2O, and on the right side, we have 2 Na atoms in Na2PO4. So, the coefficient for Na is already balanced.

Next, let's balance the phosphorus (P) atoms:

On the left side, we have 1 P atom in H2PO4, and on the right side, we have 1 P atom in Na2PO4. So, the coefficient for P is already balanced.

The balanced equation is: Na2O + H2PO4 -> Na2PO4 + ? [[3]].

6. FeS + HCl -> ? + ?

To balance this equation, let's start with the iron (Fe) atoms:

On the left side, we have 1 Fe atom in FeS, and on the right side, we have 1 Fe atom in the product. So, the coefficient for Fe is already balanced.

Next, let's balance the sulfur (S) atoms:

On the left side, we have 1 S atom in FeS, and on the right side, we have 1 S atom in the product. So, the coefficient for S is already balanced.

Finally, let's balance the hydrogen (H) atoms:

On the left side, we have 1 H atom in HCl, and on the right side, we have 1 H atom in the product. So, the coefficient for H is already balanced.

The balanced equation is: FeS + HCl -> ? + ? [[4]].

Please provide the missing products for the equations with missing information so that we can balance them accordingly.
