Among lead’s well-known developmental health effects is stunting of skeletal growth in children. Moreover, lead is known to delay fracture healing and may contribute to osteoporosis. Yet the exact mechanism by which lead affects normal cellular functions in bone and … Continue reading →

Ionic substances will not conduct electricity as solids. This is due to the fact that ions are not free to move in a solid as they are arranged in an ionic lattice. When an ionic substance is dissolved in solution … Continue reading →

Discovery of Lead Lead has been known since ancient times. We do not know who discovered it. Its ores are widely distributed and it has a low melting point so it is easily smelted. It was used in antiquity to … Continue reading →

Premium, also known as 93 octane gasoline, is the most expensive gasoline at the pump. Premium gasoline does and does not give more horsepower, depending on the type of automotive engine it is used in. How much HP does 93 … Continue reading →

Lead is used in racing fuels because it’s a very effective octane booster. As a matter of fact, leaded fuels are often credited for allowing higher compression, higher efficiency engines in World War II era aircraft. Increased power made some … Continue reading →

Glucose and alcohol does not conduct electricity in its aqueous solution state. Glucose and alcohol are non-electrolytes. They do not dissociate in aqueous solution. No current carrying ions are produced. Which of the following substances can conduct electricity? Answer: Ionic … Continue reading →

When some ionic compounds dissolve, not all of their bonds dissociate. What kind of conductivity would you expect such a solution to have? If some of the ionic compound dissolves, but not all of their bonds dissociate you would expect … Continue reading →

Lead-acid batteries have been used for more than 130 years in many different applications and they are still the most widely used rechargeable electrochemical device for small-medium scale storage applications. Do modern cars still use lead-acid batteries? Originally Answered: Why … Continue reading →

They are used in back-up power supplies for alarm and smaller computer systems (particularly in uninterruptible power supplies; UPS) and for electric scooters, electric wheelchairs, electrified bicycles, marine applications, battery electric vehicles or micro hybrid vehicles, and motorcycles. Where is … Continue reading →

A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged. Are deep-cycle batteries AGM? The … Continue reading →

Lead-acid batteries are capable of being recharged, which is important for their use in cars. Discharging the stored energy relies on both the positive and negative plates becoming lead(II) sulfate and the electrolyte losing much of its dissolved sulfuric acid. … Continue reading →
