Description

From the listing uploaded by “docman05”.

This application provides an information about important Inorganic Chemistry reactions, helps to balance chemical reactions and to calculate molecular masses of chemical compounds. The application is free and works in offline mode. The key features of the application are following: - Searching for chemical reactions by reagents and by products. - The search functionality comes together with the autocomplete functionality (so, sometimes you can type less and get the list of matched reactions). - Balancing chemical reactions. - Calculation of molecular masses of chemical compounds. - Convenient mechanism for input of chemical compound formulas. Instead of switching between small and capital letters, you can just type the whole compound formula using only small letters. For example, instead of "Na[Al(OH)4]" you can type just "naal(oh)4" (in ambiguous cases the application might ask for the clarification). Also, unlike many applications, this application can balance the complex Reduction-Oxidation reactions, which can involve a couple of simultaneous reactions. For example, the application can balance the following reaction: "Cu + Fe + HNO3 = Cu(NO3)2 + Fe(NO3)3 + NO2 + NO + H2O" (which actually consists of two simultaneous reactions: "Cu + HNO3" and "Fe + HNO3"). The applications contains plenty of important Inorganic Chemistry reactions. However, the database of chemical reactions will be updated periodically.

Chemical Reactions APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Chemical Reactions APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is c3eac804a7923d9de3ba76158d2a7742.
