Given the data below for the reaction, 2 A + 2 B + 4 C => D + E + 3 F, the reaction is first order in A, second order in B, second order in C and fifth order overall.
Experiment Initial conc of A, Initial conc of B, Initial conc of C, Initial rate,
mol/L mol/L mol/L mol/L. s 1 0.2 0.3 0.2 4 x 10-3
2 0.3 0.1 0.2 6 x 10-3
3 0.4 0.3 0.6 8 x 10-3
4 0.1 0.2 0.4 2 x 10-3

if you mean hydrogen and oxygen then water is the product

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
