Electrolysis design internal assessment Introduction to experiment Electrolysis is a method using a direct electric current to drive a non-spontaneous chemical reaction. It involves the stage in the separation of elements from naturally occurring sources such as ores. In this experiment‚ methods to alter rate of electrolysis will be attempted to be discovered. Although many contributing factors could affect the rate of electrolysis which could include internal energy within the electrolyte or

an electronic wave packet in the unifonn field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more then one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination ofparameters of such packet by powerful laser pulse scattered with is discussed. The motion of one-electron wave packet in the nonuniform

Milikan Oil Drop Experiment Objective To experimentally determine the quantum nature of charge by using the equipment especially designed for this experiment. Theory A spherical drop of oil‚ falling through a viscous medium like air‚ will quickly reach a constant velocity. When it reaches this equilibrium state‚ the viscous force is balanced by other forces acting on the drop‚ such as gravity‚ buoyant forces from the air‚ electrical forces‚ etc. In this experiment an electrical force of varying

In the 1890’s scientist found that invisible rays are emitted when matter is hit with a jolt of electricity. Such experiments involved transmitting electric arcs between two ends of cathode ray tubes. Some physicists discovered some substances that spontaneously emitted invisible rays regardless of electricity or any other type of energy. An example of these substances are: uranium and radium‚ which are named radioactive materials. X-rays were a portion of the emitted rays that had the ability to

of another atom. Ionic bond involves electron transfer across two atoms. The atom which donates the electron is called cation which is a positive ion whereas the atom which gains the electron is called anion which is a negative ion. The opposite charge of cation and anion attract one another due to the electrostatic force which is formed between them. The formation of a ionic bond involves a metal and a non-metal. Thus it forms the ionic bond. (A) EXAMPLE OF IONIC BOND (1) Sodium Chloride Sodium
