The overuse of electricity affects the ecosystem in several ways. The overuse of electricity can lead to an increased carbon footprint‚ increased climate change‚ reduction in supply‚ and high energy costs. The abiotic factors that contribute are electricity‚ smoke‚ temperature‚ climate‚ and mining. The biotic factor that affects it is people. Leaving your laptop plugged in all the time will use up 300 kilowatts an hour each year. A natural consequence of overusing energy is increased costs for you

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then
