What is obtained when an aqueous solution of aluminum chloride is heated to dryness?

The maximum velocity of the photoelectron emitted by the metal surface is $V$. The charge and mass of the photoelectron are denoted by $e$ and $m$,respectively. The stopping potential in volts is:

Two rigid bodies $A$ and $B$ rotate with rotational kinetic energies $E_A$ and $E_B$ respectively. The moments of inertia of $A$ and $B$ about the axis of rotation are $I_A$ and $I_B$ respectively. If $I_A = \frac{I_B}{4}$ and $E_A = 100E_B$,then the ratio of the angular momentum of $A$ $(L_A)$ to the angular momentum of $B$ $(L_B)$ is:

The three lines given by the combined equation $y^3 - 4x^2y = 0$ represent:

Laughing gas is prepared by heating

If $A$ and $B$ are any two sets,then $A \cap (A \cup B)$ is equal to
