Lead Acid Cell vs. Button Cell Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large

Lead is an element that occurs naturally in the environment. Small amounts of lead can be found in the earth’s crust. Most people know it to be harmful to humans but research shows that it does have some beneficial uses. Lead is found in the air‚ soil‚ water‚ and inside our homes. Much of the exposure that we receive comes from our daily activities‚ such as some types of industrial facilities‚ the use of fossil fuels and past use of lead-based paint in homes. Lead and its compounds have been used

The lab today was focused on finding the ratio of reactants to products to be either 1 to 1 or 1 to 2. In our case the reactants was Lead (II) Nitrate and Potassium Iodine. These two when mixed together make Lead Iodide and Potassium Nitrate. We also had to try and find if the number of moles of Lead(II) Nitrate was the same as the final number of moles for Lead Iodine after the experiment. Our data for the lab had pinpoint accuracy. Proved by the data table below Trials Volume of Pb(NO3)2 Mol

Hard work leads to success Hard work is the key to success. Nothing can be achieved without hard work. Work‚ work‚ ever work‚ is a great panacea. Edison worked for twenty-one hours a day. He slept only for two or three hours on the laboratory tables with his books as his pillow. Our beloved Prime Minister late Pt. Nehru‚ worked for seventeen hours a day and seven days a week.
