Convert from Real Number to Scientific Notation: 0.000345 = 3.45 x 10. Here we wish to write the number 0.000345 as a base times 10 raised to an […]
What is the device that melts if it gets too hot?
What is the device that melts if it gets too hot? An electrical fuse is a device that sacrifices itself to provide over-current protection in an electrical circuit. If too much current flows, the fuse wire rises to a higher temperature and melts, thus opening the circuit, but destroying the fuse. Does heat bend metal […]

What is the half life of a first-order reaction if time required to decrease?
What is the half life of a first-order reaction if time required to decrease? Concentration is reduced to 25%. It means it takes two half-lives to decrease the concentration of reactant from 0.8 M to 0.2 M in first-order reaction. Hence, half-life of the reaction is 12/2 = 6 hours. The half life of reaction […]
