Question

Balance the equation:

$2Na+C{l}_2\to$ ___ $NaCl$

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B

2

$2Na+C{l}_2\to 2NaCl$

We see that filling a 2 in the blank balances the equation i.e., it has 2 atoms of Na on both reactants and products side and 2 atoms of Cl on both reactants and products side.
