battery+redox+SMACK

= Jovany Marquez and Josh Alarid = =how a battery works!= =Pb + HSO4- --> PbSO4 + H+ + 2 e-= 1)When a lead-acid battery is charged, electricity is added to the battery, causing the water and lead sulfate to be combine to produce electrolyte and the active plate During normal charging, hydrogen gas is given off, however if dammage or low electrolyte gassing on the inside it creates hydrogen sulfate. A battery is an accumulator for electric energy: it can be charged with energy when the engine is running the alternator can later release the energy previously stored in it's chemical contents. The efficiency of this charge-discharge cycle depends on the quality of the battery and on the efficiency of the charger system. When the reaction takes place, both electrodes become coated with solid lead and the sulfuric acid is used up. When the automobile is turned on the alternator or generator starts producing electricity (for spark plugs, lights, car lighter and all the stuff that uses electricity the alternator or generator also recharges the battery alternator

2) lead-acid battery The basic setup




 * the negative electrode (cathode) is covered with lead (Pb)
 * and the positive electrode (anode) is covered with lead oxide (PbO2).
 * Both electrodes are immersed in a 35% sulfuric acid and 65% water solution (H2SO4 + H2O). In the electrolyte the sulfuroxide crystals H2SO4 are split into free H+ and HSO4- ions.

this picture is showing the chemical electroid reaction Anode (+) || Negative Electrode Cathode (-) || Positive Electrode Anode (+) || Negative Electrode Cathode (-) || PbSO4 + 2H2O || Pb + HSO4- PbSO4 + H+ + 2e- || PbSO4 + 2H2O PbO2 + HSO4- + 3H+ + 2e- || PbSO4 + H+ + 2e- Pb + HSO4- || 2PbSO4 + 2H2O |||| 2PbSO4 + 2H2O Pb + PbO2 + 2H+ + 2HSO4- ||

3)Battery redox reaction ingrediants- Pb is lead its it is classified as a metal.lead it is impportant in the battery because it helps the battery charge. lead has a higher charging tolerances and can be charged below freezing. HSO4 is Hydrogen sulfide When a lead-acid battery is charged, electricity is added to the battery, causing the water and lead sulfate to be combine to produce electrolyte and the active plate During normal charging, hydrogen gas is given off, however if dammage or low electrolyte gassing on the inside it creates hydrogen sulfate Sulphate. 4)this equation is important in everyday life because without it we would have to charge our car by connecting it to a eletric current. I think the equation is important because it saves us time and money, because if the battery did not charge itself we would have to connect it to an electric current in our house and it would take up energy and your electricity bill would be larger. This equation is very usefull if you think about it, it saves us time and money because if it dident charge itself we would not be able to just get in the car and drive off, we would have to charge it every night and that would be a hassel.This is a simple equation but it is very important in everybodys life because it helps us get around in our car everyday. (jovany) 5) The importance of theses reactions are that they are part of everyday life and they make life possible with the high deamand of technogie and transportion and another thing is that these reactions show what could happpen to the substance or object if left in proper spaces. these equations also show that how to make our products to last for a long time. The equations also explain how they improve our living and our knowlegde is we progress through the years and improve these chemical equations to try to prevent other reavtions that are not helpful to us to live and progress.(josh) 6)why is lead important in a redox battery - Google Search."
