This is because in liquid state water molecules are close to each other, but in an disorganised manner. Each water molecule forms around 3.4 hydrogen bonds with other water molecules. 

However, in ...

32 mmol = 0.032 mol

75cm³ = 0.075dm³

n = c x v    so   c = n / v

c = 0.032mol/0.075 dm³ = 0.426moldm^-3

pH = -log[H+]

pH = -lo...

In diamond, each carbon atom forms 4 strong covalent sigma bonds with other carbons, resulting in a tetrahedral 3D arrangement of atoms where all the electrons are fixed in place or localised. In graphite...

Sodium and Magnesium are both metals, when they are solid they form a metallic lattice held together by the electrostatic force of attractive between the positive metal ions, and the negative delocalised ...

So if we think about a molecule of ammonia, NH3, there are 3 hydrogens, each with 1 electron (as its atomic number is 1) covalently bonded to 1 nitrogen atom with 5 outer shell electrons on it due to its ...
