The measured heats of dehydration vary in the 183-614kJkg(sample)(-1) range for the various samples that present also different water vapor sorption capacities (from approximate to 0.08 to approximate to 0.14 kg(H2O) kg(sample)(-1)). The water adsorption/desorption behavior of the zeolites ...

The relative deviations between the experimental and calculated values in the density and heat capacity measurements were 0.20 % and 0.49 % for NH3 + H2O + NaOH solutions and 0.10 % and 0.36 % for NH3 + H2O + KOH solutions, respectively. Also, two density prediction methods were checked ...
The reaction between NaOH and H2SO4 is exothermic, which means it releases heat. The salt produced in this reaction, Na2SO4, is soluble in water. 中文回答: 化学方程式: 2NaOH + H2SO4 → Na2SO4 + 2H2O. 解释: 氢氧化钠(NaOH)是一种强碱,而硫酸(H2SO4)是一种强酸。当这两种化合物反应...
Re: NaOH + H2O reaction « Reply #4 on: July 18, 2007, 09:29:35 AM » Thanks for your reply!Could you say is the following prediction of the latter reaction then correct?I predict that when NaOH(s) is added into H2O(l) heat will be formed as NaOH dissociates into sodium ca...
