Question

For each of the following, predict the complete, balanced chemical equation for the reaction that occurs when they are mixed. Make sure to label the states.
1. HNO3 & NaOH
2. Sr(OH)2 & HI
..

Answer 1

Answer:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Explanation:

Hello there!

In this case, according to the given chemical reactions, it is necessary to keep in mind the cations and anions are switched around as a result of the bonds rearrangement in these neutralization reactions; therefore, we can proceed as follows:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.
