Auto battery

Maher et al. [26] describe the successful implementation of pico hydro (<5 kW) systems in two communities in Kenya. Costs for these systems were considerably less than comparable PV or auto battery systems. The systems were constructed locally using available materials and community labor. 

Total recycled thermoplastic resin production almost tripled between 1990 and 1995 and is well over 1 billion lb per year. The percentage breakdown of the amount for recycling is the following HDPE (especially bottles), 35% PET (soft drink bottles), 34% PP (auto battery cases), 14% LDPE (film), 9% PS (packaging), 3% PVC, 0.5% other, 4%. 

Another common storage battery is the lead-acid battery. The standard automobile battery is an example of a lead-acid battery. Most auto batteries of this type contain six cells that generate about 2 V each for a total output of 12 V. The anode of each cell consists of two or more grids of porous lead, and the cathode consists of lead grids filled with lead(IV) oxide. This type of battery probably should be called a lead-lead(IV) oxide battery, but the term lead-acid is commonly used because the battery s electrolyte is a solution of sulfuric acid. 

An auto mechanic spills 78 mL of 2.6 M H2SO4 solution from a rebuilt auto battery. How many milliliters of 1.5 A/ NaHC03 must be poured on the spill to react completely with the sulfuric acid [Hint H2O and CO2 are among the products.]...

The manufacture of auto batteries can introduce lead into the groundwater. The manufacture of fluorescent lamps can introduce mercury into the groundwater. 

The other type of double-displacement reaction is the reaction between an acid and a base. This double isplacement reaction, called a neutralization reaction, forms water. Take a look at the mbdng solutions of sulfuric acid (auto battery acid, H2SO4) and sodium hydroxide (lye, NaOH). Here are the molecular, ionic, and net-ionic equations for this reaction ...

Outline a risk assessment for the accidental spill of battery acid in an auto repair shop. 

By the late 1990s, it was clear that only the big automakers could make the electric car really happen. But, these were the same companies that had disdained electric cars earlier. GM once sued California in the U.S. District Court in Fresno to block imposition of the state s zero-emissions rules. These regulations would require automakers to build thousands of electric vehicles using rechargeable storage battery technology. But, the auto industry contended that conventional, electric-powered cars were too expensive and too limited in range to be profitable. 

In 1998 the auto industry turned from weak commitments to a solid move toward fuel cells and EVs. All the auto companies are pursuing hydrogen fuel cells in some way. But, the new cars on the road in the near future are likely to be a mix of vehicles including those with electric drive, including battery EVs, hybrids with gasoline and direct-injection diesels, turbo generators and fuel cells. 

Starter Solenoid Auto Bomb The starter solenoid has three terminals, one large and two small. The large one runs directly to the battery and should be avoided. An electric detonator equipped with shrouded (insulated) alligator clips is clamped to the two smaller terminals. The explosive charge itself may be attached with magnets to the underside of the car or taped to the frame. The advantage is that it requires no internal access to the... 

Occupations and exposure to lead The following occupations can expose workers to lead ammunition manufacturers (guns and bullets), auto body repairs, auto radiator repair shops, battery workers, brass/copper foundries, bridge and highway construction, cable makers, gas stations, glass manufacturers.
