The scientific study of matter's characteristics and behaviour is known as chemistry.andare 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 compounds and their composition, s...
Will there be a hydride shift in the addition reaction between HBr and 4-methylpent-2-ene? Provide the reaction mechanism for the formation of the cyclic carboxylic acid in the reaction below. What is the double replacement reaction for NaBr + Hg(NO_3)? How to determine the catalyst ...
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 ...
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...
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...

The Earth is composed of a large scale network of tectonic plates that are constantly in motion. Often, the shift is merely an inch or two each year. Sometimes forces build up over time and a shift occurs more violently as stored energy is released along faults, or in deep ocean trenches...
