In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively. periyar university phd
