Answer to: Write the balanced net ionic equation for the following reaction: NaOH(aq) + HNO3(aq) arrow H2O(l) + NaNO3(aq) By signing up, you'll get...
LiOH = H2O + NO3Li must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced. ...
NO3- Net Ionic Equation 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. 3H+(aq) + Al(OH)3(s) = Al3+(aq) + 3H2O(l) ...
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...
共轭酸碱是成对出现的,形式上相差一个质子(氢离子).酸去掉一个质子就形成其共轭碱,碱加上一个质子就形成其轭酸. HNO3的共轭碱是NO3-,NO3-的共轭酸是HNO3. OH-的共轭酸是H2O,H2O的共轭碱是OH-. 分析总结。 酸去掉一个质子就形成其共轭碱碱加上一个质子就形成其轭酸反馈...
(1)3molNO2(g)与1mol H2O(l)反应生成HNO3(aq)和NO(g),放热138kJ。(2)用CO还原1mol Fe2O3,放热24.8 kJ。(3)1molHgO(S)分解为液态汞和氧气,吸热90.7 kJ。(4)0.2mol NaOH与稀H2SO4完全反应放热11.46 kJ,写出表示酸与碱反应中和热的热化学方程式:(5)0.1g H2完全燃烧放出热量12.1 kJ,写出表示...
解答解:A、NaOH(aq)+HCl(aq)=NaCl(aq)+H2O(l)△H=-57.3kJ/mol(中和热),焓变是负值,故A错误; B、C2H5OH(l)+3O2(g)=2CO2(g)+3H2O(g)△H=-1367.0 kJ/mol(燃烧热)反应中生成 的氧化物水是气体,不是稳定氧化物,故B错误; C、S(s)+O2(g)=SO2(g)△H=-269.8kJ/mol(反应热),符合热化学...
D.CH3COOH(aq)+NaOH(aq)═H2O(l)+CH3COONa(aq)△H>-57.3kJ/mol. 试题答案 在线课程 分析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,应注意的是:①稀的酸和碱溶液,如果是浓硫酸,在和碱反应时被稀释放热;②强酸和强碱,如果是弱酸,电离吸热;③衡量标准是生成1mol水.据此分析. ...
答案解:A.由分析可知,配平后H2O的系数为9,故A错误;B.NH4NO3中,N元素化合价由铵根离子中-3价升高为氮气中0价,由硝酸根中+5价降低氮气为0价,NH4NO3失电子又得电子,则NH4NO3是氧化剂也是还原剂,故B正确;C.该反应中反应物只有一种,生成物有三种,属于分解反应,存在元素化合价的变化,属于氧化还原...
A. NaOH(aq)+HNO3(aq)═NaNO3(aq)+H2O(l)△H=+57.3kJ/mol(中和热) B. C2H5OH(l)+3O2(g)═2CO2(g)+3H2O(g)△H=-1367.0kJ/mol(燃烧热) C. S(s)+O2(g)═SO2(g)△H=-269.8kJ/mol(反应热) D. 2NO2═O2+2NO△H=+116.2kJ/mol(反应热) ...
