Question

Lexi is balancing equations. She is finding one equation to be very difficult to balance. Which explains how to balance the equation ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4?

One reactant and one product needs the coefficient 2.
The products both need a 3 coefficient.
The reactants both need a 2 coefficient.
Atoms in the equation are already in balance.

Answer 1

Atoms in the equation are already in balance.

Check element counts:
- Zn: 1 → 1
- S: 1 → 1
- Li: 2 → 2
- C: 1 → 1
- O: 4 + 3 = 7 → 3 + 4 = 7

All elements match, so no coefficients other than 1 are needed.
