Question

write a balanced equation for the reaction of na2s and cdso4. express your answer as a chemical equation. identify all of the phases in your answer. enter noreaction if no precipitate is formed. a chemical reaction does not occur for this question.

Explanation:

Step1: Write the un - balanced equation

$Na_2S(aq)+CdSO_4(aq)
ightarrow$

Step2: Predict the products

The products of the double - displacement reaction are $Na_2SO_4$ and $CdS$. So the un - balanced equation is $Na_2S(aq)+CdSO_4(aq)
ightarrow Na_2SO_4(aq)+CdS(s)$

Step3: Check the balance of atoms

On both sides of the equation, we have 2 sodium (Na) atoms, 1 sulfur (S) atom, 1 cadmium (Cd) atom, 1 sulfur (S) atom from $SO_4^{2 - }$ and 4 oxygen (O) atoms. The equation is already balanced.

Answer:

$Na_2S(aq)+CdSO_4(aq)
ightarrow Na_2SO_4(aq)+CdS(s)$
