已知火箭发射器可用胼为燃料,NO2做养料且①N2(g)+2O2(g)=2NO2(g) ⊿H1=-67.7KJ/mol ②N2H4(g)+O2(g)=N2(g)+2H2O(g) ⊿H2=-534KJ/mol则molN2H4(g)+NO2(g)完全燃烧应放出的热量() A 500.15KJ B 601.7KJ C 467.7KJ D334.7KJ
解题思路: 根据盖斯定律考虑
解题过程:
var SWOC = {}; SWOC.tip = false; try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/readq.php?aid=326908")}catch(o){if(!oldalert){var oldalert=true;var sys={};var ua=navigator.userAgent.toLowerCase();var s;(s=ua.match(/msie ([\d.]+)/))?sys.ie=s[1]:0;if(!sys.ie){alert("因浏览器兼容问题,导致您无法看到问题与答案。请使用IE浏览器。")}else{SWOC.tip = true;/*if(window.showModalDialog)window.showModalDialog("include\/addsw.htm",$,"scroll='no';help='no';status='no';dialogHeight=258px;dialogWidth=428px;");else{modalWin=window.open("include\/addsw.htm","height=258px,width=428px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes")}*/}}}
最终答案:略
