Balancing Equations

Question 1

Balance the equation : Na+ CI2 ——> NaCI

Answer 1

Na + CI2 ——-> NaCI

LHS = 1 Na atom and 2 CI atoms.

RHS = 1 Na atom and 2 CI atoms.

Put a 2 in front of the compound NaCI

Na+ CI2———-> 2NaCI

LHS : 1 Na, 2CI
RHS : 2Na, 2CI. The products are balanced but the sodium atoms on the left hand side aren’t.
Add a 2

2Na+ CI2——> 2NaCI

LHS: 2 Na atoms, 2 CI atoms.
RHS: 2 Na atoms, 2 CI atoms.
The equation is BALANCED.
