AbstractThe phase and conversion equilibria in the four-component reciprocal aqueous salt system 2NaHCOO + Ca(NO3)2 ( ightleftarrows ) Ca(HCOO)2 + 2NaNO3 –H2O at 25°С were studied. The optimum concentration parameters of the formation of calcium formate from sodium formate and calcium ...
Solution for Write the total ionic equation for Na2CO3(aq) + Ca(NO3)2(aq) → CaCO3(s) + 2NaNO3(aq)
分别测定MDA含量、质膜透性、植物鲜重、植物干重及植物体内Na+含量.实验结果表明,NaCl严重地抑制玉米的生长,而CaCl2和Ca(BO3)2均能降低由NaCl引起的抑制效应,且Ca(NO3)2优于CaCl2此外,NaCl增加细胞质膜透性、植物体内Na+和MDA含量CaCl2和Ca(NO3)2降低质膜遍性,减少植物体内Na十和MDA含量,Ca(NO3)2的这种效应好...
Development of new molten salts with LiNO3 and Ca(NO3)2 for energy storage in CSP plants In this study, the effect of the addition of LiNO3 and/or Ca(NO3)2 to the solar salt NaNO3/KNO3, which is used as a storage material in CSP plants, on the ... A.G. Fernandez,S Ushak,...
