Question

which chemical equation correctly represents the reaction between sodium and chlorine to form sodium chloride? 2na + cl2 → nacl na + cl2 → 2nacl na + 2cl2 → 2nacl 2na + 2cl2 → 2nacl

Explanation:

Step1: Recall chemical - reaction balancing

A balanced chemical equation has the same number of each type of atom on both sides of the equation. Chlorine exists as $Cl_2$ in its elemental form. Sodium ($Na$) reacts with chlorine ($Cl_2$) to form sodium chloride ($NaCl$).

Step2: Balance the sodium and chlorine atoms

For the reaction between sodium and chlorine to form sodium chloride, we need 2 sodium atoms and 1 molecule of chlorine ($Cl_2$) to produce 2 molecules of sodium chloride. The balanced chemical equation is $2Na+Cl_2
ightarrow 2NaCl$.

Answer:

No options are correct as the correct equation is $2Na + Cl_2
ightarrow2NaCl$. If we assume there was a typo in the options and the first option was meant to be $2Na+Cl_2
ightarrow 2NaCl$ (missing the 2 in front of $NaCl$), then the correct option would be the first one after correction.
