A
$H_3BO_3$ is a weak mono basic acid as it liberates hydroges ions as
$H_3BO_3 \longrightarrow H^+ + H_2BO_3^-$
B
${H_3}B{O_3}\xrightarrow{\Delta }\mathop {HB{O_2}\xrightarrow{{\operatorname{Re} d\,hot}}}\limits_{{\text{Meta Boric}}} \mathop {{B_2}{O_3}}\limits_{{\text{Boric oxide}}} $
C
$2BN + 6H_2O \longrightarrow 2H_3BO_3 + 2NH_3$
D
$Na_2B_4O_7.10H_2O + 2HCl \longrightarrow 2NaCl + 4H_3BO_3 + 5H_2O$
Solution
