Sodium carbonate(aq) + hydrofluoric acid(aq) ?
What is the formula for the complete chemical equation?
Na2CO3(aq) + 2HF(aq) ==> H2O(l) + CO2(g) + 2NaF(aq)
The formula for the complete chemical equation between sodium carbonate (Na2CO3) and hydrofluoric acid (HF) is:
Na2CO3(aq) + 2HF(aq) → 2NaF(aq) + H2O(l) + CO2(g)
To determine the complete chemical equation for the reaction between sodium carbonate and hydrofluoric acid, we need to look at the chemical formulas of the reactants and products involved.
The chemical formula for sodium carbonate is Na2CO3, where Na represents sodium, C represents carbon, and O represents oxygen. Sodium carbonate is a solid compound that dissolves in water to form a solution.
The chemical formula for hydrofluoric acid is HF, where H represents hydrogen and F represents fluorine. Hydrofluoric acid is a liquid compound that also dissolves in water to form a solution.
When these two compounds react, they will undergo a double-displacement reaction, forming water and a new compound.
The balanced equation for the reaction is:
Na2CO3(aq) + 2HF(aq) → 2NaF(aq) + H2O(l) + CO2(g)
In this equation, the coefficients indicate the number of moles of each compound involved in the reaction. The (aq) denotes that the compound is in aqueous (dissolved in water) form, (l) represents a liquid, and (g) signifies a gas.
So, when sodium carbonate reacts with hydrofluoric acid, it produces sodium fluoride, water, and carbon dioxide gas.
