Answer:
H₃PO₄ + 5HCl → PCl₅ + 4H₂O
Explanation:
A chemical equation is a representation of a chemical reaction, wherein the reactants are written on the left side and the products on the right side of a chemical equation.
In writing a chemical equation, the chemical names of substances involved in a chemical reaction are written in symbolic form. If you do not know how to write the chemical formula of a substance, kindly refer to the topic "Chemical Formula Writing".
The word "and" in the statement above will be replaced by the plus (+) symbol. When you also see the word "reacted with" or "combined with" , it will also replaced by the plus (+) symbol.
The word "yield" will be substituted by the right arrow (→) symbol. Other keywords for the word "yield" are "produced", "obtained", etc.
Therefore, the statement, when replaced with symbols and formulas, becomes
H₃PO₄ + HCl → PCl₅ + H₂O
In balancing chemical equations, you must keep in mind that the number of each atom in the reactant side must be equal to the number of each atom in the product side in accordance with the Law of Conservation of Mass.
The balanced chemical equation now becomes
