nignag [31]

Answer:

Sodium will an electron and chlorine will gain an electron

Explanation:

The electronic configurations of sodium and chlorine are;

Sodium- 1s2 2s2 2p6 3s1

Chlorine- 1s2 2s2 2p6 3s2 3p5

Hence, sodium can easily loose one electron to chlorine to attain a noble gas configuration while chlorine accepts one electron to attain the noble gas configuration.

Balanced chemical equation for the decomposition of solid sodium sulfide in aqueous solution.
Oliga [24]
<h3>Answer:</h3>

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

<h3>Explanation:</h3>

We need to know:

<h3>What are decomposition reactions?</h3>
  • Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
  • When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
  • When this happens the soluble compound such as ionic compounds ionizes to form ions.
  • This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
  • For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
  • That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
