Problem- Determine the element of lowest atomic number that contains a complete d subshell in the ground state.
I want to know how this is done please show all steps in detail
determine the pressure inside a container of a gas connected to an open-end manometer filled with ccl4 has the density
Initial Concentration of azomethane Initial rate Exp. 1 1.13 x 10-2 M 2.8 x 10-6 M/s Exp. 2 2.26 x 10-2 M 5.6 x 10-6 M/s
If a nail made of elemental iron [Fe(s)] is placed in an aqueous solution of a soluble palladium (II) salt [Pd2+(aq)], the nail will gradually disappear as the iron enters the solution as Fe3+ (aq) and palladium metal [Pd (s)] forms.
The standard enthalpy of atomization of an element is the energy necessary to convert one mole of an element in its stable form at 25 degree Celsius to one mole of monoatomic gas.
