This application includes added support for inserting parentheses for polyatomic ions and brackets for charges in oxidation/reduction reactions.
For an equation containing polyatomic ions, if there is only one molecule of the ion, such as in H(NO3), DO NOT insert the parentheses, and instead input HNO3.
For a redox equation, make sure that every compound has a bracket with a charge, even if a compound has no charge. For a positive charge, for example, input , for a negative charge, [-2], and for a charge of 0, . DO NOT INPUT [+2].
C6H12O6 + O2 = CO2 + H2O
H2 + O2 = H2O
AgI + Pb(NO3)2 = AgNO3 + PbI2
Ca(OH)2 + (NH4)3PO4 = Ca3(PO4)2 + NH4OH
Cr2O7[-2] + H + Fe = Cr + H2O + Fe
Cu + Ag = Cu + Ag
This application operates offline, without the use of the Internet, by solely using mathematical algorithms to find coefficients of compounds.
If you encounter any issues with the application, feel free to contact me via email (email@example.com). I am always open to suggestions that will improve the quality of this application. Otherwise, happy balancing!
NOTE: Please read the "Help" section under the menu on the application for additional and detailed instructions. This application does not solve equations. It only balances complete equations with compounds on both sides. Invalid equations entered will cause errors to be thrown.
"Hadronic". Hadrons are the particles inside the atomics nucleus such
as protons and neutrons. Hadronic physics is a branch of Nuclear and
Particle Physics that describes the structure and interactions of
Hadrons. The principles of Quantum Physics and Quantum Field Theory
are employed to compute the properties of hadrons and the forces

This Android app is a demonstration of the use of Hadronic Physics
techniques. It is also a demonstration of the computational power of
smartphones and tablets. The goal is to compute the binding energy of
the helium nucleus (He-4 isotop) and of nuclear matter (hypotetical
nucleus with infinite particles) starting with experimental
information of the interaction between protons and neutrons.
The input information are the experimental data of neutron-proton
scattering. A beam of neutrons with some incident energy interact and
are scattered by a proton (Hidrogen) target, and precise meassurements
of the number of neutrons for each scattering angle are performed.
This information can be codified in quantities called "phaseshifts",
representing the shifts in the phase of the scattered neutron
wave. Neutrons are described by waves in quantum physics. The wave
function of a neutron is computed in this app by solving the
Schroedinger equation. To solve this equation we must know the force
between neutrons and protons (np), which is represented by a function
called "the potential energy" or, simply, "the np potential".
HADRONICA main screen
In the main screen there are eleven field text
with parameters that the user can change to control
some aspects of the calculations.
The four numbers R0,lambda0,R1,lambda1 in the first column
are the parameters of the np interaction in the 1S0 channel.
The four numbers R0,lambda0,R1,lambda1 in the second column
are the parameters of the np interaction in the 3S1 channel.
The three numbers in the last row control several aspects of
the fitting algorithm:
E_max: is the maximum incident energy entering in the fit
Tolerance: is the minimum experimental error allowed for the pseudodata
Resolution: controls when the optimal set of parameters is found.
The potential parameters are modified inside a loop. For each set of
parameters we compute the total distance from the theoretical
phaseshifts to the experimental data until the minimum distance is
found. In each step of the loop, the parameters are allowed to move
in a discrete grid. The distance between adjacent points in the grid
is reduced recursively by one half until the value of the resolution
is reached. Note that by this procedure one can reach local
minima. Experimenting with different starting points and different
resolutions can produce different results.
The calculation in this app is performed in four stages,
fired the user by pressing the four buttons A--D.

** For anyone who wants to contribute to this project, please look for "Chemical Pal (Donate)" in our other apps. Your support is greatly appreciated! **
NOTE: The Internet access privilege is for collecting app data usage only, in order for us to find out what features you like best and what issues you may have with the application. We do NOT collect personal data and will NOT serve you advertisements!
Please consider reviewing or commenting; reviews and comments help us decide what features to add next! If you want to see something, don't stay quiet; chances are, someone else wants it, too!
The app provides four features. The first is a Periodic Table of the Elements, which is color-coded for different element types. You can tap each square to get basic info, or tap its full name to get the data sheet on it.
The second is a mass calculator, that allows you to input any formula, such as "Al(SO4)3", and receive the relative atomic mass of such a compound. Additionally, typing in the name of a single element (such as "Hydrogen") will yield the mass of that element.
ChemPal also provides an elementary Reaction Balancer, including electrons (and compound charges)!
Finally, you can browse a list of all elements in the periodic table and view their name, elemental index, and weight. By tapping on one, you access our third feature, the elemental data sheet, which provides weight, density, boiling point, melting point, electron configurations, and more. Also provides a link to Wikipedia.
If you are an international user and notice any errors in translations (my native language is English), please either write a review or email me--I'd like to eliminate these errors as soon as possible!

This app provides a visual approach to organic chemistry. It is not meant to replace a textbook - it should be seen as a visual aid. The molecules and reactions are just briefly described. The main focus are the numerous animations of the molecules and reactions. Currently only alkanes, alkenes and alkynes are described. You can test your knowledge through a quiz of 40 questions.
IMPORTANT: Hardware requirements - SCREEN SIZE > 3.7 inches and DUAL-CORE CPU!
The animations are strongly compressed in order to keep the app size small. This is why the animations only run on newer smartphones!
It's a new version of app "Chemical reactions"
The app is designed for offline search inorganic reactions.
How to use the application.
For example, if you want to find a response, on the left side which Al, you need to enter a query Al or Al =.
If you want to find the reaction on the right side which MnO2, you need to enter a query = MnO2.
Find a reaction in which the left part of NaOH and H2: make a request NaOH H2 or NaOH H2 =.
Find a reaction in which the left side of KMnO4, and the right K2SO4: make a request KMnO4 = K2SO4.
Attention! Case letters in the query affect the result. That is, if you enter "naoh", as a result of reaction with the participation of "NaOH" will not be found!
It covers all you need to know to understand chemistry concepts. The chemistry practical exposes you to periodic table and dilution calculation.
Complete chemistry offers a quiz section for evaluating your knownledge and ares you need to improve in chemistry.
The app also has a note section where you can save notes of items you want to remember or a summary of certain concept.
