3. Assuming the reaction took 75 seconds, calculate the relative rate of reaction 1000/t 4. A student repeated the experiment and mixed the following reactants 10.0 mL of 0.10 M KI, 10.0 mL of 0.0010 M Na2S2O3, 10.0 mL of 0.040 M KBrO3, 10.0 mL of 0.10 M HCl and 10 mL of H2O. It took 155 seconds for the mixture to turn blue. Calculate concentrations of each reactant in the

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
