Question

pls help! no explanation needed
Which of these chemical equations describes an acid-base neutralization reaction?
1) 2Al(s) + 3H₂SO₄(aq) --> Al₂(SO₄)₃(aq) + 3H₂(g)
2) SO₂(g) + H₂O(l) --> H₂SO₃(g)
3) LiOH(aq) + HNO₃(aq) --> LiNO₃(aq) + H₂O(l)
4) CaBr₂(aq) + H₂SO₄(aq) --> CaSO₄(s) + 2HBr(g)

Answer 1

Answer:

Option 3.

LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)

Explanation:

To know which option is correct, we must have an ideal of what is acid–base neutralization.

Neutralization is a reaction involving an acid and a base which produces salt and water only.

With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.

From the question given above, only the 3rd equation gas water as part of the products i.e

LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)

Hence, equation 3 is an acid-base neutralization reaction
