he two reactions involved in quantitatively determining the amount of iodate in solution are: IO3-(aq) + 5 I-(aq) + 6 H+(aq) --> 3 I2(aq) + 3 H2O(l) followed by reaction of the I2: I2(aq) + 2 S2O32- --> 2 I-(aq) + S4O62-(aq). What is the stoichiometric factor, that is the number of moles of Na2S

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

How could a student test the effect of removing heat from a gas that is stored in a sealed container? what must occur in order for matter to change states?
