Using the flexibility and power of Excel, this book offers a novel approach to learning the fundamentals of chemical equilibria. The text allows readers to produce and digest large assemblies of numerical data/calculations while still focusing on the chemistry. It has been designed both as a supplement to an undergraduate quantitative analysis course or as a text in a graduate-level advanced analytical chemistry course. Professional chemists will also find this to be an excellent introduction to spreadsheet applications in the lab and a modern overview of analytical chemistry in a self-study format. The authors include problems at the end of each chapter.

Trykt eller digital bog?

Ud over trykte bøger tilbyder vi tre forskellige typer af digitale bøger:

 

Vital Source Bookshelf: En velfungerende ebogsplatform, hvor bogen downloades til din computer og/eller mobile enhed.

 

Du skal bruge den gratis Bookshelf software til at læse læse bøgerne - der er indbygget gode værktøjer til f.eks. søgning, overstregning, notetagning mv. I langt de fleste tilfælde vil du samtidig have en sideløbende 1825 dages online adgang. Læs mere om Vital Source bøger

 

Levering: I forbindelse med købet opretter du et login. Når du har installeret Bookshelf softwaren, logger du blot ind og din bog downloades automatisk.

 

 

Adobe ebog: Dette er Adobe DRM ebøger som downloades til din lokale computer eller mobil enhed.

 

For at læse bøgerne kræves særlig software, som understøtter denne type. Softwaren er gratis, men du bør sikre at du har rettigheder til installere software på den maskine du påtænker at anvende den på. Læs mere om Adobe DRM bøger

 

Levering: Et download link sendes pr email umiddelbart efter købet.

 


Ibog: Dette er en online bog som kan læses på udgiverens website. 

Der kræves ikke særlig software, bogen læses i en almindelig browser.

 

Levering: Vores medarbejder sender dig en adgangsnøgle pr email.

 

Vi gør opmærksom på at der ikke er retur/fortrydelsesret på digitale varer.
