Firstly, using Beer-Lambert's equation. It is noted, that absorption is equal to the molar extinction coefficient, multiplied by the path length of light, multiplied by the concentration of the solution.T...

In order for metals to bond they need to loose electrons to ensure that they have a full outer shell and become positively charged. The positive cations (metal ions) are attracted to the negatively charge...

In essence, a dative covalent bond is just a covalent bond with an unpaired electron, therefore, shared between two atoms in a delocalised manner. An example of this is Carbon monoxide, which is formed in...

For each element on the periodic table there are two key numbers associated with it, the atomic number and the atomic mass (top and bottom respectively). The atomic number is simply a count of how many pr...

21.5 cm³ / 1000 = 0.0215 dm³ of HCl. n = cv so (0.050) x (0.0215) = 0.001075 mols of HCl. NaOH + HCl --> NaCl + H₂O so there is a 1:1 ratio of reactants to products. Th...
