Combination Reaction
No, the reaction between Na2S and HCl does not involve a single replacement reaction. Instead, it is a double displacement reaction where the cations and anions of the two compounds switch partners to form new compounds.
The balanced chemical equation for the reaction between sodium chloride (NaCl) and potassium iodide (KI) is: 2NaCl + KI → NaI + KCl. This equation ensures that there is the same number of each type of atom on both sides of the reaction.
When potassium chloride (KCl) reacts with sodium carbonate (Na2CO3), a double displacement reaction occurs. The potassium ions (K+) switch places with the sodium ions (Na+), resulting in the formation of potassium carbonate (K2CO3) and sodium chloride (NaCl). The balanced chemical equation for this reaction is 2KCl + Na2CO3 → K2CO3 + 2NaCl.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
The balanced equation for CaSO4 + 2NaCl is CaCl2 + Na2SO4.
You bet it is. Na2CO3 + 2HCl ==> 2NaCl + H2O + CO2
Yes, the reaction 2Na + Cl2 → 2NaCl is an example of a combination reaction. In a combination reaction, two or more substances react to form a single product. In this case, sodium (Na) and chlorine (Cl2) combine to form sodium chloride (NaCl).
The balanced chemical equation for the reaction between Na2SO3 (sodium sulfite) and HCl (hydrochloric acid) is: Na2SO3 + 2HCl -> 2NaCl + H2O + SO2
single replacment
An exothermic chemical reaction.
This is a single displacement reaction, where zinc (Zn) replaces sodium (Na) in sodium chloride (NaCl) to form zinc chloride (ZnCl2) and sodium (Na) metal. The reaction is also known as a displacement or substitution reaction.
The reaction between 2NaCl and H2SO4 is a double displacement reaction, where the sodium (Na) from NaCl exchanges places with the hydrogen (H) from H2SO4 to form Na2SO4 and HCl. This reaction generally involves the swapping of ions between two compounds.

The balanced chemical equation for the reaction between sodium chloride (NaCl), carbon dioxide (CO2), and water (H2O) is: 2NaCl + CO2 + H2O → 2HCl + Na2CO3
The reaction between Na2CO3 (sodium carbonate) and HCl (hydrochloric acid) produces NaCl (sodium chloride), H2O (water), and CO2 (carbon dioxide). The balanced chemical equation for this reaction is: Na2CO3 + 2HCl -> 2NaCl + H2O + CO2.
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.
