Balance the following equation: underline ( )Na+underline ( )Cl_(2)arrow underline ( )NaCl

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />Given equation: $\underline {\quad }Na+\underline {\quad }Cl_{2}\rightarrow \underline {\quad }NaCl$<br /><br />Step 1: Count the number of atoms of each element on both sides of the equation.<br /><br />On the left side:<br />- Sodium (Na): 1 atom<br />- Chlorine (Cl): 2 atoms<br /><br />On the right side:<br />- Sodium (Na): 1 atom<br />- Chlorine (Cl): 1 atom<br /><br />Step 2: Balance the chlorine atoms by placing a coefficient of 2 in front of NaCl on the right side.<br /><br />$\underline {\quad }Na+\underline {\quad }Cl_{2}\rightarrow 2\underline {\quad }NaCl$<br /><br />Step 3: Balance the sodium atoms by placing a coefficient of 2 in front of Na on the left side.<br /><br />$2\underline {\quad }Na+\underline {\quad }Cl_{2}\rightarrow 2\underline {\quad }NaCl$<br /><br />The balanced chemical equation is:<br />$2Na + Cl_{2} \rightarrow 2NaCl$<br /><br />Answer: $2Na + Cl_{2} \rightarrow 2NaCl$
