this formula equation is unbalanced.\nbacl₂(aq) + na₂co₃(aq) → baco₃(s) + nacl(aq)\nwhich coefficient should be placed in front of nacl to balance this equation?\no 1\no 2\no 3\no 4
Answer
Explanation:
Step1: Count atoms on left - hand side
On the left side of the equation $BaCl_2(aq)+Na_2CO_3(aq)\rightarrow BaCO_3(s)+NaCl(aq)$, we have 1 Ba atom, 2 Cl atoms, 2 Na atoms, 1 C atom and 3 O atoms.
Step2: Analyze atoms on right - hand side
On the right side, we have 1 Ba atom, 1 Cl atom, 1 Na atom, 1 C atom and 3 O atoms.
Step3: Balance Cl and Na atoms
To balance the Cl and Na atoms, we need 2 moles of NaCl on the right - hand side since we have 2 Cl atoms and 2 Na atoms on the left - hand side.
