Statement I is false because chlorine has the most negative electron gain enthalpy in its group. Statement II is true as oxygen has the least negative electron gain enthalpy in its group.
The Correct Answer is: Statement I is false but Statement II is true
For the reaction, $H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$
Attainment of equilibrium is predicted correctly by:
The remainder when \( 64^{64} \) is divided by 7 is equal to:
x mg of Mg(OH)$_2$ (molar mass = 58) is required to be dissolved in 1.0 L of water to produce a pH of 10.0 at 298 K. The value of x is ____ mg. (Nearest integer) (Given: Mg(OH)$_2$ is assumed to dissociate completely in H$_2$O)
