The results of the analysis showed that the students had limited understanding of chemical reactions, while their answers indicated that they accumulated extended declarative knowledge, which had not been assimilated. Taking into consideration that students had repeatedly studied ‘redox’ reactions, both ...
For example, how students use a chemical model may be a latent variable for which both the correct and incorrect answers to particular questions in an assessment can serve as markers or indicators of understanding. Using the language of construct reminds us that when assessing student understanding...

this study answers an important fundamental question about the surface interaction-associated processes that drive the mechanism of 2D nanomaterials’ bioremediation as well as provides the fundamental basis for further short- and long-term investigations on the environmental effects of inorganic crystalline...
Since ORP is a thermodynamic measurement, water temperature matters. The colder the water, the slower chemical reactions like oxidation and reduction can occur, thus the ORP decreases. The warmer the water, things speed up, and the ORP increases. ...
-VOCs gradually enriched. For example, in summer, the observed concentration of survivable ethylene (one of the reactive species) is low, but its contribution to O3is relatively great of all species. The idea of survivor bias answers the question that why the concentration between M-VOCs and ...
Molecules, being composed of bonded atoms, can undergo chemical reactions as well. The nature of these reactions depends on the types of atoms involved and the bonds between them. Molecules can react to form new compounds, break apart into their constituent atoms, or rearrange their atomic compos...
This detailed time-resolved, in situ, quantitative NMR analysis answers three central questions about Ca3SiO5 hydration: the molecular origin of the reduced apparent solubility of Ca3SiO5 during the induction period, the possible 'switch' from one type of hydration products to another between the ...
