Question

How do you write out the equation for this reaction: Sodium phosphate reacts with calcium nitrate to produce sodium nitrate plus calcium phosphate?

Answer 1

Hint: Chemical reactions are the reactions which represent the chemical change by the help of a symbol of elements or atom. In a chemical reaction, a chemical change is observed by various means like formation of precipitate, evolution of gas etc.

Complete step by step answer:
Chemical change is the change in which reactants react together to form products. Chemical change can be observed by the following characteristics
1.During a chemical change either a solid precipitate forms.
2.During a chemical change either gas evolves.
3.During a chemical change either color of solution changes.
4.During a chemical change temperature of the solution either gets increased or decreased.
For example- When zinc metal dissolves or reacts with a green solution of ferrous sulfate the color of the solution changes from green to colorless due to the formation of zinc sulfate and it is one of the examples of chemical change.
In the given question sodium phosphate reacts with calcium nitrate to give sodium nitrate and calcium phosphate.
Let us first discuss the molecular formula of the entire given compound.
Calcium nitrate $ - Ca{(N{O_3})_2}$
Sodium nitrate $ - {\operatorname{NaNO} _3}$
Calcium phosphate $ - C{a_3}{(P{O_4})_2}$
Sodium phosphate $ - {\operatorname{Na} _3}P{O_4}$
Balanced chemical equation:
$2N{a_3}P{O_4} + 3Ca{(N{O_3})_2} \to 6NaN{O_3} + C{a_3}{(P{O_4})_2}$
Final answer:
The final balanced chemical reaction is as follows:-
$2N{a_3}P{O_4} + 3Ca{(N{O_3})_2} \to 6NaN{O_3} + C{a_3}{(P{O_4})_2}$

Note: We can also make the chemical equation more informative by adding the following information. For example
1.We can add the physical state of both reactant and products like solid, liquid and gas.
2.We can add concentration of solution also like dilute and concentrated solution.
3.We can add reaction conditions also on the single headed arrow which represent the appropriate condition for a particular reaction.
4.We can also represent the formation of gas by upward arrow while formation of precipitate by downward arrow.
