Na2S + 2HCl = 2NaCl + H2S (smelly toxic gas)
Sodium sulphide + hydrochloric acid => Salt (Sodium chloride) and Hydrogen sulphide
When HCl is added to Na2S, hydrogen sulfide gas (H2S) is formed. This gas has a characteristic rotten egg smell and is toxic in high concentrations.
The balanced equation is 2HCl + Na2S → H2S + 2NaCl. This is balanced as the number of atoms of each element is the same on both sides of the equation.
There will be no reaction. It will remain a mixture.
The balanced chemical equation for CdBr2 + Na2S is: CdBr2 + Na2S → CdS + 2NaBr
When hydrochloric acid (HCl) reacts with iron powder, the iron oxidizes to form iron(II) chloride (FeCl2) and hydrogen gas (H2) is released. This reaction is a typical metal-acid reaction known as a single displacement reaction. The iron powder will dissolve and you will observe bubbling as the gas is released.

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.

No, Na2S (sodium sulfide) is a basic compound. When dissolved in water, it forms hydroxide ions which makes the solution basic.
using the equation M1V1 = M2V2, V2 = M1V1/M2 = 1 x V/ 0.5 basically, whatever volume of 1M HCl you have, add the same mount of water and you will dilute it to 0.5M.
Na2S(aq) + ZnCl2(aq) --> 2NaCl(aq) + ZnS(s)
