Explanation:
a) We have to write the unbalanced chemical equation for the reaction between Na metal and Cl₂ gas to produce solid NaCl. The unbalanced reation will be:
Na (s) + Cl₂ (g) ---> NaCl
b) In a balanced chemical equation we have the same number of atoms of each element on both sides of the equation.
In our equation we have 1 atom of Na and 2 atoms of Cl on the left, and on the right we have 1 Na atom and 1 Cl atom.
So this equation is unbalanced because we have different number of Cl atoms on both sides of the equation.
Answer:
a) Na (s) + Cl₂ (g) ---> NaCl
b) So this equation is unbalanced because we have different number of Cl atoms on both sides of the equation.
