The magnesium ion is in group two of the periodic table, whereas sodium is in group one. This means that magnesium has one more proton than the sodium ion, so it has a more positive core. Both ions have t...
1 dm3 of ethanol is equal to 1000 cm3, so the mass of ethanol used is =density x volume = 0.789 g cm-3 x 1000 cm3 = 789gMolar mass of ethanol = (2x12)+(6x1) +(1x16)= 46 g mol-1Moles of ethanol = mass/mola...
Firstly a transition element is an element which forms one or more stable ions with incompletely filled d orbitals.Ligands are charged or neutral, ions or molecules, which form coordination bonds with a c...
A reaction is said to be feasible or spontaneous when the Gibbs Free Energy (Delta G) of the reaction is <0. Conversely, when the Gibbs Free Energy (Delta G) of the reaction is >0,...
The first ionisation energy depends on:the charge on the nucleus, the distance of the outer electron from the nucleus, the amount of shielding by inner electrons and whether the electron is alone in an or...
