25.4 g of iodine and 14.2g of chlorine are made to react completely to yield a mixture of ICl and \(\mathrm{ICl_3}\) Calcualte the ratio of moles of ICl and \(\mathrm{ICl_3}\)

This question uses stoichiometry and limiting reagent. Write the balanced chemical equation, compute moles of each reactant, identify the limiting reagent, and use stoichiometric ratios (and % yield, if needed) to obtain the answer; this gives option A.
