It has a giant lattice structure, strong covalent bonds are difficult to break etc.

X with 2,4 DNPH (Brady's reagent) is used to show the presence of an aldehyde or ketone. X also reduces Copper ions (Fehling's) meaning it has to be an aldehyde and not a ketone as ketones are not readily...

These sorts of questions can look difficult, but if you learn the steps needed to solve them then they are all very similar.Step 1: Since we are told that X is a carbohydrate, we know tha...

We know that the reaction is a 2:1 ratio as 2 moles of NaNO3 is used to form 1 mole of O2 so first we need to find the moles of the product produced 
SoVolume of gas (dm3)= number of moles x 24dm3The...

The first ionisation energy of an element is the minimum energy required to remove a single electron from one mole of an element in its gaseous state. As you go down the group the first electron becomes e...
