Question

Write proper symbols for x and y in the following chemical equation.

$\mathrm{Fe}\left(x\right)+{\mathrm{Zn}}^{2+}\left(\mathrm{aq}\right)\to {\mathrm{Fe}}^{2+}+\mathrm{Zn}\left(y\right)$

Answer 1

Physical state:

The physical state is the state of matter in which the compound or molecules exist. This can be expressed in a balanced chemical equation. The symbols in the given chemical reaction equation represent the physical state of the substance.

Symbols for x and y:

Both Iron (Fe) and Zinc (Zn) exist in the solid state represented by s and the ions exist in the aqueous state represented by aq. The complete chemical reaction equation is given below.

$$\begin{gathered} \mathrm{Fe}\left(\mathrm{s}\right)+{\mathrm{Zn}}^{2+}\left(\mathrm{aq}\right)\to {\mathrm{Fe}}^{2+}\left(\mathrm{aq}\right)+\mathrm{Zn}\left(\mathrm{s}\right) \\ \mathrm{Iron}\mathrm{Zinc}\mathrm{ions}\mathrm{Iron}\mathrm{ions}\mathrm{Zinc} \end{gathered}$$
