</span><span>Li⁺ (aq) + OH⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → Li⁺ (aq) + Cl⁻ (aq) + H₂O(l)</span><span />
<span>Explanation:
</span>
<span>1) Combine the cation Li⁺ (aq) with the anion Cl- (aq) to form LiCl(s).
</span>
<span>LiCl is a solid soluble substance, a typical ionic compound. So, it will reamain as separate ions in the product side: Li⁺ + CL⁻</span>
<span>2) Combine the anion OH⁻ with the cation H⁺ to form H₂O(l).
</span>
<span>Since, the ionization of H₂O is low, it will remain as liquid in the product side: H₂O(l)</span>
<span>3) Finally, you can wirte the total ionic equation:
</span>
Li⁺ (aq) + OH⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → Li⁺ (aq) + Cl⁻ (aq) + H₂O(l)
The list that only includes terms that describe Cesium (Cs) is option (b) i.e atom, element, pure substance .
<h3>
What do you mean by the term atom , element, pure substance ?
</h3>
Atom, is the smallest unit of matter that has the characteristic properties of a chemical element .The atom is the basic building block of chemistry.
Element is a pure substance consisting of only one type of atom which all have the same numbers of protons. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
Hence ,in the list that only includes terms that describe Cesium (Cs) is option (b) i.e atom, element, pure substance .
