The number of moles is related to the amount of a substance we have. If we were to use the number of particles, the numbers would be huge and impractical to use. So, Avagadro's number provides us a link w...

There are 5 main factors that affect the rate of reaction. 1. Concentration: Increasing the concentration increases the frequency of collisions between particles. 2. Surface Area: Increasing the surface a...

Same molecular formulas, but bonded in different ways. So by this I mean that 2 molecules could have the same formula but have a different structure, they have bonded together differently.

because increasing the temperature will increase the kinetic energy of molecules, hence there is more collisions between the molecules and more molecules having the IE above the activation energy

Copper has a [Ar]4s1 4d10 whereas Chromium has a [Ar]4s14d5 electron configuration as this d shell configuration of either half full d shell (5 electrons) with only one electron per orbital or fully full ...
