Answer»

Solution :a . `B(OH)_(3)+NH_(3)overset(Delta)(to)UNDERSET(("Boron nitride"))(BN)+3H_(2)O`
b. `Na_(2)B_(4)O_(7)+H_(2)SO_(4)+5H_(2)Oto underset(("Boric acid"))(4H_(3)BO_(3))+2Na_(2)SO_(4)`
c.`B_(2)H_(6)+2NaOH+2H_(2) O to underset(("Sodiummeteborate"))(4NaBO_(2))+6H_(2)`
(d) `B_(2)H_(6)+6CH_(3)OHtounderset(("Trimethyl borate"))(2B(OCH_(3))_(3))+6H_(2)`
e. `4BF_(3)+9H_(2)Oto underset(("BOric acid"))(4H_(3)BO_(3))+3H^(+)+3[BF_(4)]^(-)`
f. `HCOOH+H_(2)SO_(4)to underset (("Carbon MONOXIDE"))(CO)+H_(2)O+H_(2)SO_(4)`
g. `SiCl_(4)+NH_(3)underset("ether")(330K)(to) Cl_(3)Si -underset(("Chlorosizalanes"))(NH)-SiCl_(3)`
h. `SiCl_(4)+C_(2)H_(5)OH to underset(("Tetraethoxy silane"))(Si(OC_(2)H_(5))_(4)+2Cl_(2)`
(i) `2B+6NaOHto underset(("SODIUM borate"))(2B_(2)O_(3))+H_(2)O`
j. `H_(2)B_(4)O_(7) overset("Red HOT")(to)underset(("Boric anhydride"))(2B_(2)O_(3))+H_(2)O`
