is oxidized and thus causes reduction ELECTROCHEMISTRY INVOLVES TWO MAIN TYPES OF PROCESSES: A. Galvanic (voltaic) cells – which are spontaneous chemical reactions (battery) B. Electrolytic cells – which are non-spontaneous and require external e− source (DC power source) C. BOTH of these fit into the category entitled Electrochemical cells GALVANIC CELLS Parts of the voltaic or galvanic cell: o Anode--the electrode where oxidation occurs. After a period of time‚ the anode may appear to become smaller

the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the solution in a period of 10 minutes

Research about LM317 Positive Adjustable Linear Voltage Regulator: The LM317T is a 3-terminal integrated circuit which can supply a load current of up to 1.5 Amps with an output voltage of between 1.2V and 37 Volts. It accepts an input voltage of between 3 and 40 volts. It can be used to regulate either current or voltage in situations where a fixed current or fixed voltage is required. The level of current or voltage required can be adjusted by connecting the chip in series with a fixed resistor

are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house

ANALOG CIRCUIT DESIGN VOLTAGE REGULATOR USING OP-AMP PROJECT REPORT By T.SAI KUMAR (12BEC0116) S.GIRISH(12BEC0253) K.VISHWANATH(12BEC0459) V.KARTHIK(12BEC0440) VOLTAGE REGULATOR USING OP-AMP ABSTRACT In real life situations‚ we come across many scenario where we require a constant output voltage even though the input voltage is varying randomly .Voltage regulator is the device which produces constant output voltage for varying input. Generally in many of the household appliances

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

Introduction I am going to try and measure the rate of respiration in yeast and find out what factors affect the rate of respiration. I am going to change the concentration of the glucose solution and I’m going to measure the volume of gas produced during respiration in cm³. Yeast contains enzymes. Enzymes speed up a chemical reaction – they’re biological catalysts. Yeast can respire both aerobically and anaerobic; the anaerobic respiration of yeast is known as fermentation. The equation for

Singh Manvir Case 1: 1. What options does Hi-Voltage have for developing a system to connect with Green Industries’ purchasing system? Hi-Voltage has a option to develop a business to business transaction processing system to facilitate the electronic data interchange (EDI) that Green Industries recently installed. By developing a new order entry system Hi-Voltage will improve efficiency and strengthen its bond with Green Industries. 2.
