Symbol equations for reactions are written using chemical formulae.
The symbol equation for the reaction between iodine and hydrogen is: I2 + H2 -> 2HI.
If no reaction occurs between the substances, then there is no need to write an equation. Equations are used to represent chemical reactions, so if no reaction is taking place, an equation is not required.
The balanced symbol equation for the reaction between potassium and chlorine is: 2K + Cl2 → 2KCl.
To write a complete ionic equation for a chemical reaction, first write the balanced molecular equation. Then, break down all the ionic compounds into their respective ions. Include only the ions that are involved in the reaction. Finally, write the complete ionic equation by showing all the ions present before and after the reaction.
To write an ionic equation, first write the balanced chemical equation for the reaction. Then, separate the soluble ionic compounds into their respective ions. Finally, eliminate the spectator ions that do not participate in the reaction to form the net ionic equation.
The symbol equation for the reaction between iodine and hydrogen is: I2 + H2 -> 2HI.
The symbol equation for the reaction of sulfur with oxygen is: S + O2 → SO2

The symbol equation for the reaction between chlorine and sodium bromide is: Cl2 + 2NaBr → 2NaCl + Br2.
To write the formula for barium bromide (BaBr₂) as a chemical equation, you need a reaction. For instance, the reaction between barium chloride (BaCl₂) and sodium bromide (NaBr) would form barium bromide and sodium chloride (NaCl): BaCl₂ + 2NaBr → 2NaCl + BaBr₂.
With this symbol:
Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
The symbol equation for the reaction of magnesium with oxygen to form magnesium oxide is: 2Mg + O2 -> 2MgO
