Answer 1

Answer: (A)

$\left(A\right)\to \left(ii\right),\left(B\right)\to \left(iv\right),\left(C\right)\to (i0,(D)\to (iii)$

Answer:- (A) $\left(A\right)\to \left(ii\right),\left(B\right)\to \left(iv\right),\left(C\right)\to \left(i\right),\left(D\right)\to \left(iii\right)$

(A) Borax $\to$ Also known as sodium tetraborate decahydrate have chemical formula ${Na}_2{B}_4{O}_7.10H_{2}O\left(ii\right)$.

(B) Inorganic benzene $\to$ Borzine is known as inorganic benzene. It's chemical formula is $B_3{N}_3{H}_6\left(iv\right)$.

(C) Cryolite $\to$ Earlier it was used as an ore of aluminium and later in the electrolytic processing of the aluminium-rich oxide ore bauxite. It's chemical formula is ${Na}_{3}Al{F}_6\left(i\right)$.

(D) Bauxite $\to$ Bauxite is a sedimentary rock with a relatively high aluminium content. Its chemical formula is ${Al}_2{O}_3.2H_O\left(iii\right)$.
