Answer:
Explanation:
Hello,
This problem could be solved in terms of normality as follows:
- The normality of phosphoric acid (triporitic) is:
Thus, the normality of barium hydroxide turns out:
Finally, the molarity:
Best regards.
Explanation:
The reaction is given as;
Pb ( N O ₃ ) ₂ (aq) + K I (aq) → Pb I ₂ + K N O ₃
To ensure the reaction is balanced, there has to be equal number of toms of each element present in both the reactant and product side of the reaction.
This leads us to;
Pb ( N O ₃ ) ₂ (aq) + 2 K I (aq) → Pb I ₂(s) + 2 K N O ₃(aq)
Ths way all atoms of elements are the same.
<span>Elements in Period 2 such as Barium and Beryllium can lose up to two electrons when they react, however Boron can lose up to three electrons when it reacts which causes it to break the pattern normally seen in Period 2.</span>
