The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. OH-(aq) + H+(aq) = H2O(l) ...
For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis () or brackets []. How To Balance Equations Balance any equation or reaction ...
uptake of HNO3 and H2Orocket emissions[1] The goal of this study is to quantify uptake of H 2 O and HNO 3 by and estimate their residence time on alumina particles in Athena-2 rocket plumes. This study uses in situ measurements made in the lower stratosphere with the NASA WB-57F high...

强酸强碱的稀溶液发生中和反应生成1mol水时放出的热量为57.3kJ.下列热化学方程式正确的是( )A. HNO3(aq)+KOH(aq)═H2O(l)+KNO3(aq)△H>-57.3kJ/mol.B. HNO3(aq)+NH3•H2O(aq)═H2O
B、HNO3(aq)+NaOH(aq)═NaNO3(aq)+H2O(l),该反应属于复分解反应,不是氧化还原反应,所以不能设计成原电池,故B选;C、2H2(g)+O2(g)═2H2O(l),该反应属于自发的氧化还原反应,所以能设计成原电池,故C不选;D、Zn(s)+Ag2 O(s)═Zn O(s)+2Ag(s),该反应属于自发的氧化还原反应,所以能设计成原...
中和热是在稀溶液中,强酸、强碱发生中和反应生成1mol水时放出的热量,中和热为57.3kJ/mol.下列热化学方程式中正确的是( )A. HNO3(aq)+KOH(aq)═H2O(l)+KNO3(aq)△H>-57.3 kJ/molB.
分析:Fe+HNO3=Fe(NO3)2+NO↑+H2O中,Fe元素的化合价由0升高为+2价,硝酸中N元素的化合价由+5价降低为+2价,以此来解答. 解答: 解:(1)N元素的化合价降低,则氧化剂为HNO3;Fe失去电子被氧化,则氧化产物为Fe(NO3)2,故答案为:HNO3;Fe(NO3)2; (2)Fe失去电子,N得到电子,3molFe反应转移6mol电子,则反应及...
