Dear Roy:
I am writing from Argentine. I am very interested in the materuial you have
offered but i Could not open the attach file. Could you please send a new
mail for me again?
Thank you
Best regards

> THE VISCHEM RESOURCES - Details
>
> Firstly, there are the three videos (see illustrated video scripts on the
> VisChem Web page) which link lab observations - like ice melting, NaCl
> dissolving, AgCl precipitating, acetic acid dissociating, iron
> isothiocyanate complexing, and silver ions reducing to silver atoms on
> copper - to animations portraying these changes at the molecular level.
> These animations are then linked to the formulas and equations involved.
> The videos are designed to be shown in short segments when dealing with
> specific reactions.
>
> Secondly, all the VisChem animations are available on a CD as
> cross-platform Quicktime movie files that can be put onto your
> institution's computers for assignments, or into your own non-commercial
> software purposes. They cannot be put on the Web (the files are too big
> anyway!).

>
> Abstract:
> This program uses molecular level animations to portray -
>
> * sodium chloride dissolving in water;
> * hydrated ions in sodium chloride solution
> * the difference between sodium chloride melting and dissolving;

D-ROM ----------------------------------------------------------
>
>
> 1. VisChem CD No. 1 - Molecular World of Reactions in Water:
> Substances and Reactions in Water
>
> Format:
> CD ROM (WIN and Mac compatible)
>
> Abstract:
> The first CD in the series contains all the animations used in videos 1, 2
> and 3 listed above, plus others, together with the building-block
animations
> that support them, all in a cross platform Quicktime file format.
>
> The molecular level animations portray -
>
> * pure substances like copper, sodium chloride and oxygen;
> * selected phase changes like ice melting;
> * reactions in solution such as dissolution, precipitation,
> complexation, acid/base hydrolysis, and oxidation/reduction.
>
> They are available for insertion as movies or frame grabs into computer
slide
> presentations, word processing documents, and computer assisted learning
> software. The CD interface shows each animation with a short description.
> A flow chart illustrates the relationship between the animations, and the
> information section gives suggestions on how they can be used. The CD has
a
> direct link to the VisChem Web site.
