HOW DO YOU BALANCE NH4CL + Na2SO4

You can't as it is not an equation.

To balance the chemical equation NH4Cl + Na2SO4, you need to ensure that the same number of each type of atom appears on both sides of the equation. Here's how you can balance it step by step:

1. Count the number of each type of atom on each side of the equation:
NH4Cl: 1 N, 4 H, 1 Cl
Na2SO4: 2 Na, 1 S, 4 O

2. Start by balancing the metals (Na):
Add a coefficient of 2 in front of Na2SO4, which results in:
NH4Cl + 2 Na2SO4

3. Next, balance the non-metal elements (N, H, Cl, and S) one by one:
N: Currently, there is only 1 N atom on the left, so we need to balance it by adding a coefficient of 2 in front of NH4Cl:
2 NH4Cl + 2 Na2SO4

H: There are 8 H atoms on the left (4 H atoms in NH4Cl and 4 H atoms in Na2SO4), so we need to add a coefficient of 4 in front of NH4Cl to balance them:
4 NH4Cl + 2 Na2SO4

Cl: There are now 4 Cl atoms on the left (4 Cl atoms in NH4Cl), and we need to balance them. Add a coefficient of 4 in front of NaCl to balance the Cl atoms:
4 NH4Cl + 4 Na2SO4

S: There is now 2 S atom on the right (from the 2 Na2SO4), so we need to add a coefficient of 2 in front of NH4Cl to balance it:
8 NH4Cl + 4 Na2SO4

Now the equation is balanced with 8 NH4Cl + 4 Na2SO4. Each side of the equation has the same number of atoms for each element, and the equation is balanced.
