Identify the reactants and the products in the following chemical equation:
Cd(NOsub3)sub2(aq)+Hsub2S(g)-->CdS(s)+2HNOsub3(aq)
What do you think? I will be happy to critique your thinking
I don't know how to do it. We didn't go over it in class, and so I'm really confused on what to do.
In order to identify the reactants and products in the given chemical equation, we need to understand the notation used for the substances involved.
- The notation (aq) represents an aqueous solution, meaning the substance is dissolved in water.
- The notation (g) represents a gaseous state.
- The subscripts following the symbols indicate the number of atoms or ions present. For example, (NOsub3)sub2 means there are two NO3 ions.
- The arrow (→) separates the reactants from the products, indicating the direction of the chemical reaction.
Now let's break down the equation and identify the reactants and products:
Reactants:
1. Cd(NOsub3)sub2(aq) - This is an aqueous solution of cadmium nitrate, represented by Cd(NO3)2. It contains Cd2+ ions and NO3- ions.
2. Hsub2S(g) - This represents hydrogen sulfide in its gaseous state, denoted by the formula H2S. It consists of two hydrogen (H) atoms and one sulfur (S) atom.
Products:
1. CdS(s) - This represents cadmium sulfide in its solid state, denoted by the formula CdS. It consists of one cadmium (Cd) atom and one sulfur (S) atom.
2. 2HNOsub3(aq) - This represents nitric acid in its aqueous solution form, denoted by HNO3. It contains H+ ions and NO3- ions. The subscript 2 indicates that two of these entities are present.
Therefore, the reactants in the chemical equation are Cd(NO3)2(aq) and H2S(g), while the products are CdS(s) and 2HNO3(aq).
