Two species that transform into each other by loss or gain of a proton. 

The equation for the reaction is; 2H₂ +O₂ = 2H₂O

From the equation it can be seen that 2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles...

Lets say we have 0.89 mol dm-3 of CH3COOH, a weak acid, with a ka of 1.7X10^-5.We want to find Ph, but to do this we first need to know [H+] because PH = -log10[H+].Because CH3COOH is a weak acid, it only...

Covalent bonding happens when two molecules share a pair of electrons. For example in hydrogen chloride (HCl). Ionic bonding is when two oppositely charged ions are attracted to each other to form a la...

Due to the delocalisation of electrons in the benzene ring conferring more stability on the structure.
