Chapter 9.3, Problem 55SSC

Interpretation Introduction

Interpretation:

For the given reaction, complete and balanced equation needs to be determined.

$\text{Ba}{\left(\text{OH}\right)}_{\text{2}}\left(\text{aq}\right)\text{+2HCl}\left(\text{aq}\right)\to$

Concept introduction:

For balancing an equation first write the skeleton equation. After that count, the atoms of both side, each polyatomic ion is count as a single element. Find the correct coefficient and placed them in front of the atoms and checked both side element equal or not.

Answer to Problem 55SSC

The complete and balance equation is $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}\left(\text{aq}\right)\text{+2HCl}\left(\text{aq}\right)\to {\text{BaCl}}_{\text{2}}\left(\text{aq}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{l}\right)$.

Explanation of Solution

Now, write the complete equations for the reaction.

$\text{Ba}{\left(\text{OH}\right)}_{\text{2}}\left(\text{aq}\right)\text{+2HCl}\left(\text{aq}\right)\to {\text{BaCl}}_{\text{2}}\left(\text{aq}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{l}\right)$

All atoms present on both sides of the reactants and products are equal. Therefore, the balanced equation is $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}\left(\text{aq}\right)\text{+2HCl}\left(\text{aq}\right)\to {\text{BaCl}}_{\text{2}}\left(\text{aq}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{l}\right)$

Conclusion

The complete and balance equation is $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}\left(\text{aq}\right)\text{+2HCl}\left(\text{aq}\right)\to {\text{BaCl}}_{\text{2}}\left(\text{aq}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{l}\right)$.
