balance:

CaCl2 + AgNO3 → AgCl + Ca(NO3)2

this don't make cents to me, just its so confusing

CaCl2 + 2AgNO3 → 2AgCl + Ca(NO3)2

To balance the chemical equation CaCl2 + AgNO3 → AgCl + Ca(NO3)2, follow these steps:

Step 1: Count the number of atoms for each element on both sides of the equation.

On the left side:
Ca: 1
Cl: 2
Ag: 1
N: 1
O: 3

On the right side:
Ag: 1
Cl: 1
Ca: 1
N: 2
O: 6

Step 2: Start by balancing the elements that appear in the fewest number of compounds.

In this case, begin with Ag, as it appears in only one compound on each side.

CaCl2 + AgNO3 → AgCl + Ca(NO3)2

Step 3: Add coefficients to balance the atoms on each side.

CaCl2 + 2AgNO3 → 2AgCl + Ca(NO3)2

After adding the coefficients, recheck the number of atoms on each side:

On the left side:
Ca: 1
Cl: 2
Ag: 2
N: 2
O: 6

On the right side:
Ag: 2
Cl: 2
Ca: 1
N: 2
O: 6

Now the equation is balanced, with the same number of atoms for each element on both sides.

To balance the given chemical equation:

CaCl2 + AgNO3 → AgCl + Ca(NO3)2

we need to ensure that the same number of each type of atom is present on both sides of the equation.

First, we can start by balancing the metal atoms. On the left side, we have one calcium (Ca) atom, and on the right side, we also have one calcium atom. Therefore, the calcium atoms are already balanced.

Next, let's move on to the chlorine (Cl) atoms. On the left side, we have two chloride (Cl) ions, while on the right side, we have one chloride (Cl) ion. To make the number of chlorine atoms equal on both sides, we need to put a coefficient of 2 in front of AgCl:

CaCl2 + AgNO3 → 2 AgCl + Ca(NO3)2

Now, let's balance the nitrogen (N) atoms. On the left side, we have one nitrogen (N) atom in AgNO3, and on the right side, we have one nitrogen (N) atom in Ca(NO3)2. The nitrogen atoms are already balanced.

Finally, let's balance the silver (Ag) atoms. On the left side, we have one silver (Ag) atom in AgNO3, and on the right side, we have two silver (Ag) atoms in 2 AgCl. To make the number of silver atoms equal on both sides, we need to put a coefficient of 2 in front of AgNO3:

CaCl2 + 2 AgNO3 → 2 AgCl + Ca(NO3)2

Now, the chemical equation is balanced.
