We need to find the value of X (the water of crystallisation) and to do this we can start by calculating the moles of water lost and the moles of the anhydrous salt (the salt product without water), we do...

Because the plane of the C=O bond in an aldehyde is flat, and so the nucleophilic attack of CN^- onto the C can occur above or below the plane of the molecule, producing two different stereoisom...

Firstly, we have to understand what a buffer is. A buffer is a solution which resists changes in pH when small amounts of acid or base are added. The key word here is small amounts, as if too much acid or...

For the zeroth order reaction, the graph would be a straight line with a negative gradient. For the first order reaction, the graph would be a curve with constant half-life. That means the time for the co...
