Sulfur reacts with fluorine to produce three different compounds. the mass ratio of fluorine to sulfur for each compound is given in the following table:
compound mass f : mass s
s2f10 2.962
sf4 2.370
sf6 3.555
show that these data are consistent with the law of multiple proportions.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
