Q. ${aK}_{2}{Cr}_{2}O_{7} + bKCl + {cH}_{2}{SO}_{4} \longrightarrow x{CrO}_{2}{Cl}_{2} + yKHSO_{4} + zH_{2}O.$ The above equation balances when
A) $a\$= 2, b = 4, c = 6 and $x = 2,y = 6,z = 3$
B) $a = 4,b = 2,c = 6$ and $x = 6,y = 2,z = 3$
C) $a = 6,b = 4,c = 2$ and $x = 6,y = 3,z = 2$
D) $a = 1,b = 4,c = 6$ and $x = 2,y = 6,z = 3$
Explanation
(d)
$aK_{2}{Cr}_{2}O_{7} + bKCl + cH_{2}{SO}_{4} \longrightarrow x{CrO}_{2}{Cl}_{2} + y{KHSO}_{4} + zH_{2}O\$
