A) \[b=\hat{i}+\hat{j}\]
B) \[a.c=|c|,|c-a|=2\sqrt{2}\]
C) \[\text{a}\times \text{b}\]
D) \[|(a\times b)\times c|\]
Correct Answer: A
Solution :
The equation of required line is \[K[{{H}_{2}}O]=\frac{[R-\overset{+}{\mathop{N{{H}_{3}}}}\,][O{{H}^{-}}]}{[RN{{H}_{2}}]}\] \[{{K}_{b}}=\frac{[R-\overset{+}{\mathop{N{{H}_{3}}}}\,][O{{H}^{-}}]}{[R-N{{H}_{2}}]}\]\[p{{K}_{b}}=-\log {{K}_{b}}\] \[CaC{{l}_{2}}\] \[NaCl\] \[N{{a}_{2}}C{{O}_{3}}\]\[C{{a}^{2+}}\] \[CaC{{O}_{3}}\] \[CaO\]Lines are mutually perpendicular. Hence, the angle between lines is \[NaCl\]
