1) If the level of water in the eudiometer is above that in the cylinder, is the pressure in the eudiometer higher or lower than the atmospheric pressure?

2) Why do we put the magnesium in a copper basket? (why not some other metal?)

3) What are possible sources of error?

4) For each of the following experimental or calculations errors, tell of the calculated value of R, writte if would be too high, too low or unchanged.EXPLAIN

a) Some air bubbles were introduced when the eudiometer was inverted.

b) The magnesium was coated with magnesium oxide.

c) Some of the hydrogen gas is dissolved in the water (hint: if it is dissolved, it wont be a bubble!)
