Answer:
3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.
Explanation:
- Double replacement reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
- The reaction between CaCl₂ and Na₃PO₄ is:
<em>3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.</em>
<em></em>
Ca replaces Na in (Na₃PO₄ ) and forming Ca₃(PO₄)₂.
Na replaces Ca in CaCl₂ and forming NaCl.
<em>So, the products of this reaction are Ca₃(PO₄)₂ and NaCl.</em>

Answer:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Explanation:
Abbreviated and unabbreviated electronic configuration:
The abbreviated electronic configuration uses the noble gas configuration i.e complete electronic shells. For example, the atomic number of neon is ten and sodium is eleven. The abbreviated electronic configuration of sodium is written by using the neon abbreviation in following way:
The electronic configuration of neon is given below:
Ne₁₀ = 1s² 2s² 2p⁶
The abbreviated electronic configuration of sodium:
Na₁₁ = [Ne] 3s¹
While the unabbreviated electronic configuration is written without using noble gas electronic configuration.
Unabbreviated electronic configuration of sodium:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
A. atoms because they are all matter and matter is made up of atoms
