\(SnO_2\) and \(PbO_2\) are amphoteric.
Identify the correct statement about the oxidation states of group 14 elements
Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion (A): \([SiF_6]^{2-}\) is formed but \([SiCl_6]^{2-}\) is not
Reason (R): Electronegativity \((EN)\) of \(F\) is higher than \(EN\) of \(Cl\)
In the light of the above statements, choose the correct answer from the options given below
The portion of the line \( 4x + 5y = 20 \) in the first quadrant is trisected by the lines \( L_1 \) and \( L_2 \) passing through the origin. The tangent of an angle between the lines \( L_1 \) and \( L_2 \) is:
