A hybrid motor coupled with a 2.5-liter four-cylinder Atkinson-cycle gasoline engine with 246 total system horsepower and 233 lb.-ft. of torque is teamed with a high-output, low-resistance nickel-metal hydride battery that offers a high level of output and fuel economy. The 216-cell battery...
The scientific study of matter's characteristics and behaviour is known as chemistry.Chemistry vocabularyandChemistry glossaryare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up ...
What is the mechanism behind this reaction? What is the structure and IUPAC name Explain the mechanism of Fischer esterification for the formation of ethyl ethanoate. Which of the following carbocation's is (are) likely to undergo rearrangement through a hydride shift? a.I b.II c.III d.I ...
While the lithium-ion battery will continue to be improved, the near future is unlikely to see an industry shift away from a well-understood technology. Lithium-ion batteries have the following benefits: They have a higher energy density than either conventional lead-acid batteries used in ...
Modifying a petrol engine to use less fuel, then using it to power the car AND as a generator to charge a battery, then using the power in that battery to drive an electric motor to help move the car. Bewildering. Yet such is the inefficiency of a regular petrol engine, this ro...
Acetanilide is less reactive than aniline toward electrophilic substitution. Explain. Which of the following carbocation's is (are) likely to undergo rearrangement through a hydride shift? a.I b.II c.III d.I and II e.II and III Show the mechanism of electro...
Cell voltage: Each lithium-ion cell has a voltage of approximately 3.6 volts. This has many benefits. The voltage of each lithium-ion cell is greater and in many battery applications, it requires fewer batteries, being higher than the typical nickel-cadmium, nickel-metal hydride, and even stan...
Regenerative braking changes the electric motor to a generator that captures the kinetic energy of the wheels when the brake is applied, storing it in the nickel-metal hydride (NiMH) hybrid battery pack. In EV drive mode, under certain conditions, the NX 300h can run solely on the electric ...
