Balance H2O + Na2O = NaOH Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in H2O + Na2O = NaOH must...
摘要: Na2O,Na2O2的性质——与H2O,CO2反应往往采取对比的方法学习,增补"Na2O,Na2O2与CO2反应"的实验,可增强实验的直观性,学习的趣味性,便于知识的掌握与巩固,弥补了中学教材(试验修订本*必修)中未安排"酸性氧化物与碱性氧化物反应"实验的不足,并可以作为指导学生开展研究性学习的素材.关键词:...
The phase evolution and microstructural development of a series of geopolymer mixtures comprising SiO2, Al2O3, Na2O and H2O prepared by alkali reaction of metakaolin, have been studied. The study also included the effects of cure duration and its impact on physical properties such as compressive ...

Depending upton the composition of the reaction mixture, mordenite or ZSM-5 can be synthesised in the absence of the organic additive. The ferrierite phase is formed over a wide range of gel compositions although the yield and purity of the sample is dependent upon the aluminium content of the...

Sodium release rates were 30% slower in D2O compared to rates in H2O; but matrix dissolution rates were unaffected. These results are consistent with rupture of the O-H bond as the rate-limiting reaction in Na+-H+ exchange whereas matrix dissolution is controlled by OH- or H2O catalyzed ...
Sodium aluminosilicate hydrate (N-A-S-H) gel, the main reaction product of the alkali-activated aluminosilicates, differs of the aluminium-modified calcium silicate hydrate (C-A-S-H) gel of PC pastes. Increasing the level of SCM to reduce PC content of binders are being considered to addres...
