Each carbon atom forms 3 covalent bonds (not it's maximum 4) so the one outer shell electron left is free to move within the structure. These delocalised electrons can carry electrical charge.

Question: Why is water formed when acids react with alkalis in a neutralisation reaction?
because the acid contains hydrogen and the base contains oxygen

Question: Why is water formed when acids react with alkalis in a neutralisation reaction?
because the ionic equation is: H+ + OH- --> H2O? So for example: NaOH + HCl --> NaCl + H2O Na+ + OH- + H+ + Cl- --> Na+ + Cl- + H2O
Na+ and Cl- are spectator ions so the only ones that change are H+ and OH- which form H2O?
How can an ester be made from glucose? (6mks - think C1 + C3)
- fermentation of glucose by yeast to form ethanol and carbon dioxide - ethanol is distilled to purify it - alcohol + carboxylic acid (+ strong acid catalyst) <--> ester + water - so add carboxylic acid to this ethanol produced to produce ester? never seen something like this so idk
Yes but remember a carboxylic acid can be made by oxidising a primary alcohol. So you can take half of the alcohol produced, oxidise it, add it to the original = ester
Describe the main stages of the Haber Process [4 marks]
Nitrogen from the air and hydrogen from natural resources are mixed together in a closed machiene. They mix to make ammonia in the machiene and make liquid ammonia, this is condensed to form liquid ammonia which is filtered off. Remaining hydrogen and nitrogen are reused and mixed again.

Contains free electrons which carry the electronic charge throughout the metal..
What is the structure of diamond??
Diamonds are giant covalent structures Each carbon atom will form four covalent bonds in a rigid structure which makes diamond the hardest natural substance
Q: if i dissolved a small amount of solid in water,added sodium hydroxide and a red/brown precipitate formed.. What would the cation be?
