Chapter 19, Problem 43R

To determine

To explain: The representation of the substance in an equation is a solid.

Answer to Problem 43R

The right answer is option C −Solid.

Explanation of Solution

Introduction:

Especially for the ionic reactions, the physical states of the chemical in a reaction is stated in parenthesis after the chemical symbol.

The physical states of the chemical in a reaction is stated in parenthesis after the chemical symbol, generally in the ionic equations. Let us consider a chemical equation with its physical state representation such as,

  $\text{A}\left(\text{s}\right)\text{+B}\left(\text{g}\right)\to \text{AB}\left(\text{s}\right)$

Here, in the parenthesis, the physical states of the reactants and products are stated.

In a chemical equation, the physical states of the solid denoted by $\left(\text{s}\right)$ , that of liquid by $\left(\mathrm{l}\right)$ , that of gas by $\left(\mathrm{g}\right)$ and that of aqueous by $\left(\text{aq}\right)$ .

Conclusion:

Thus, if a substance in an equation is solid, is represented by $\left(\text{s}\right)$ .
