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.

Explanation:

Step1: Count atoms on reactant side

On the reactant side of $ZnSO_4 + Li_2CO_3
ightarrow ZnCO_3+Li_2SO_4$, for zinc ($Zn$) there is 1 atom, for sulfur ($S$) there is 1 atom, for oxygen ($O$) there are $4 + 3=7$ atoms, for lithium ($Li$) there are 2 atoms and for carbon ($C$) there is 1 atom.

Step2: Count atoms on product side

On the product side, for zinc ($Zn$) there is 1 atom, for sulfur ($S$) there is 1 atom, for oxygen ($O$) there are $3 + 4 = 7$ atoms, for lithium ($Li$) there are 2 atoms and for carbon ($C$) there is 1 atom.

Answer:

D. Atoms in the equation are already in balance.
