Question

For questions 22 – 24, write an equation for the reaction of hydrogen chloride and sodium sulfide to produce hydrogen sulfide with sodium chloride.

22. Show the formulas of the reactants.
23. Show the formulas of the products.
24. Write the balanced the equation for this reaction

Answer 1

Step-by-step explanation:

1) Formulas of the reactants:

Hydrogen chloride : HCL

Sodium sulfide :
`Na_2S`

2) Formulas of the products:

Sodium chloride : NaCl

Hydrogen sulfide :
`H_2S`

3) Balance chemical equation is given as:

`2HCl+Na_2S\rightarrow 2NaCl+H_2S`

2 moles of hydrogen chloride reacts with 1 mole of sodium sulfide to produce 1 mole of hydrogen sulfide along with 2 moles sodium chloride.

Answer 2

Step-by-step explanation:

We can a lot of information from the names of the compounds given. This is the basis of solving this problem.

Formulas of the reactants:

Hydrogen Chloride is HCl

Sodium Sulfide is Na₂S

Formulas of the products:

Hydrogen sulfide is H₂S

Sodium chloride is NaCl

Balanced reaction equation:

HCl + Na₂S → 2NaCl + H₂S
