WebThat's their heats of formation. So Hess's Law tells us that delta H of this reaction, the change in enthalpy of this reaction, is essentially going to be the sum of what it takes to decompose these guys, which is the minus heat of formations of these guys, plus what it takes to reform these guys over here. So we can just write it as delta H of ... WebH2O (molar mass is 18.015 g/mol ), it implies we have a percent composition of H and one for O . Given that chemical formula, we have twoequivalents of H , for which we can use its molar mass, MH=1.0079 g/mol . We also have one equivalent of O , for which we can use its molar mass, MO=15.999 g/mol . The percent composition (by mass) of H maybe many of us like reading https://balbusse.com
