Question

Sodium sulfide reacts with hydrochloric acid to produce hydrosulfuric acid and sodium chloride. (you need to write and balance the equation to answer the question.) How many moles of sodium chloride can be produced from 2.50 moles hydrochloric acid?

Answer 1

2.5 moles of NaCl

Step-by-step explanation:

The balanced chemical reaction equation is shown in the image. Since it takes 2 moles of Hydrochloric acid to form two moles of sodium. Chloride, then 2.5 moles of hydrochloric acid should also form 2.5 moles of sodium chloride according to the balanced reaction equation.
