A catalyst is something that speeds up the rate of reaction, without being consumed during the reaction. If a catalyst is used in a reaction, it will only speed up the forward and backward reaction, howev...

C atomic mass-12 C percentage by composition: 53% Atomic ratio of C: 53/12= 4.417 H atomic mass-1 H percentage by composition: 3.9% Atomic ratio of H:...

Xenon is further down Group 8 of the Periodic Table than Neon, hence has its outermost electrons in higher energy shells further away from the nucleus. Therefore, there are more full inte...

For a reaction to be feasible at a given temperature, it must happen spontaneously, which means no extra energy needs to be put in for the reaction to occur. To find out whether a reaction is feasible, yo...

By definition, to be a transition metal, is a d block metal, which forms at least one stable ion, with a partially filled 3d shell.
Scandium has one stable ion, Sc³⁺, which posses no 3d o...
