Question

Examine the reactants of the incomplete double-displacement reaction. 2NaCl + H2SO4 → __________. Which of the answer choices correctly predicts the product of the double-displacement reaction?

Answer 1

Im doing this in my bed & don't have my periodic table with me to check the solubility but I'll go with my memory..

2NaCl(aq) + H2SO4(aq) -> Na2SO4(s) + 2HCl(aq)

Remember: like-replaces like!

Answer 2

Answer: sodium chloride
`NaCl` and sulphuric acid
`H_2SO_4` are reactants .

sodium sulphate
`Na_2SO_4` and hydrochloric acid
`HCl` are products.

Step-by-step explanation:

Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. Reactants are written on left side of the arrow.

Products are defined as the substance which are formed at the end of the chemical reaction.Products are written on the right side of the arrow.

Double displacement reaction is one in which exchange of ions take place.

`2NaCl(aq)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2HCl(aq)`

Thus sodium chloride
`NaCl` and sulphuric acid
`H_2SO_4` are reactants and sodium sulphate
`Na_2SO_4` and hydrochloric acid
`HCl` are products and all are present in aqueous (aq) state.
