So what the giants of science teach us is to see ourselves modestly and not to overrrate ourselves.
Hans Adolf Krebs, 1900-1981

- In q 4 hcl is limiting so hydrogen should be half of mole of hcl..?
- Hello Xiaodan, I think you have put it very well and are correct. Students intuitively realise that energy needs to be put in to break a chemical bond but it is less obvious that the same amount of energy is given out when the same bond is...
