Question

A reaction takes place between sodium chloride andhydrochloric acid. The products of this reaction are sodium sulfate(Na2SO4) and hydrochloric acid. What is thebalanced equation that represents this reaction? (a) NaCL + H2 SO4   Na2SO4 +HCL (b) 2NaCL +H2SO4   Na2SO4+ HCL (c) @NaCL + H2SO4 Na2SO4 + 2HCL (d) NaCL +H2SO4      Na2SO4 +2HCL A reaction takes place between sodium chloride andhydrochloric acid.

Explanation / Answer

I'm assuming you meant the reaction between sodium chloride andsulfuric acid because that is the only way to get the products inthe answers you have listed. NaCl + H2SO4--->Na2SO4 + HCl Now we need to balance the equation: There are 2 sodium ions on the right so there must be 2 on theleft. The same goes for the hydrogen. Thus, the equation becomes: 2NaCl + H2SO4--->Na2SO4 + 2HCl Hope that helps!
