The program allows you to create images useful in the work of a chemist. The most important of its functions include:      * The ability to independently create designs for structural and submitting them to the finished components supplied with the program.      * presentation of the structures in two and three dimensions.      * the ability to create equations and reaction pathways of synthesis with the use of structural models and        aggregated.      * The ability to draw chemical equipment through its "submission" with ready-made elements.      * The ability to independently create different types of chemical graphics, such as kinetic curves.

                        

The program in its basic version is free for noncommercial use and can be downloaded from the manufacturer. The paid version is extended on the dictionary containing the chemical structural formula and a summary of chemical compounds. want to try on your own?download here.

the beauty of HTML

HTML, which stands for HyperText Markup Language, is the predominant markup language for web pages. A markup language is a set of markup tags, and HTML uses markup tags to describe web pages. HTML is written in the form of HTML elements consisting of "tags" surrounded by angle brackets (like ) within the web page content. HTML tags normally come in pairs like and . The first tag in a pair is the start tag, the second tag is the end tag (they are also called opening tags and closing tags).The purpose of a web browser is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page. HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create href="http://en.wikipedia.org/wiki/Structured_document" title="Structured document">structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts in languages such as JavaScript which affect the behavior of HTML webpages. HTML can also be used to include Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both HTML and CSS standards, encourages the use of CSS over explicit presentational markup.
