CH1010 Study Guide - Quiz Guide: Dinitrogen Tetroxide, Hypoiodous Acid, Hydrogen Cyanide
Document Summary
Name the following, or give the chemical formula. Friday sept 8/2017 and monday sept 11/2017 iron (ii) perchlorate or ferrous perchlorate. H2s(aq) ammonium sul de chromium (iii) hypoiodite or chromic hypoiodite. Hg2(cn)2: hydrogen gas can be produced from the reaction of a metal hydride and water. Cah2(s) + 2 h2o( ) ca(oh)2(s) + 2 h2(g) (a) which species is the limiting reagent if you mix 5. 323 g of cah2 with 4. 982 g of water? solution. The moles of cah2 present is 5. 323 g/42. 10 g/mol = 0. 1264 mol. From the 1 cah2 to 2 h2o stoichiometry, we can say that. 0. 1264 mol of cah2 will react with 0. 2528 mol of h2o. We have 0. 2765 mol of h2o, so we have more. H2o than what is needed to consume all of the cah2. We say that cah2 is the limiting reagent, while. H2o is the excess reagent. (b) what mass of hydrogen gas can be formed from the resulting reaction? solution.
