How would the results be made more percise? (1)
Giving data to 3dp rather than 2dp
Calculate the mean average for these results? (2)
Give to examples of experimental errors that could have been made? (2)
Why is it important to repeat each experiment? (1)
To get more reliable accurate results
Diagram you had to complete of N and Cl covanetly bonded together
What kind of bonding is this? (1)
Diamond are very hard, why is this. Include information on the bonding and structure of diamonds? (3)
Giant covalent bond
Particles tight together
Strong intermolecular forces
What does a precipitate recation mean?
A solid is produced
How would you get the (solid product - cant remember the name :L) seperate?
What happens in the seperator?
Why is stage 4 needed?
If heat energy applied to this rection decreases then the amount of amonia made increases, why is this? (1)
Because its an exothermic reaction
The manufacturers increase the pressure to (high number) why dont they go over this? (1)
What is the percentage of amonia made from the possible amount? (1)
Why does it not matter that its a low percentage made?
Because the unreacted nitrogen and hydrogen are recyled to go through the process again.
Explain the structure and bonding of gold? (3)
Overlapping outter shell of electrons
Tightly packed together particles
Why is gold a good conducture of electricity? (2)
Electrons from outter shells have pathways through whole metal structure
Iron surface corrodes when exposed to air, this reduces its ability to conduct, explain why? (2)
If there is 20m of nitrogen how much hydrogen would you need?
how much ammonia could you make with 2g of nitrogen?
Why when pressure is increase does the amount of ammonia increase?
Complete this equation Ca = Ca2+ + ?
Ca = Ca2++ 2e-
Why is this described as oxidation?
Electrons are lost
What ion makes soluton acidic?
Which ion make soltuion alkaine?
Why do the chloride ions go to the positive electorde
Whats the mass of the gass?
Theres also some rfm question in there too but cant quite remember
