WINTER 1994 PAPER 6 :)
Question 9
IN SHORT
they say :1. Compare the amounts of energy given out by 2 different types of coal.
2.Outline an experiment to show whch coal contains most sulfur dioxide !
pretty hard to be honest. for me anyway..goodluck asnwering them.

Try using a rubber bung, glass tube and syringe for the second one.
In comparing the amounts of energy. As we all know, combustion is an exothermic reaction, and heat is given out in an exothermic reaction, we may wish to measure the temperature change in the surroundings for that ...
WARRIOR:
Apparatus
: 20cm3 of water in a copper can + thermo ..{int. temp + final temp] temp should rise to 50* and then stop experiment
: Same mass of coals.
: Bunsen burner
: final mass of coal
result. : the coal whch decreased my less aamount produces most energy
for the first question ^ By the way
