Chemical Reactions vs Geometry

Chemical Reactions is an ultimate tool for balancing chemical reactions, combining of the multistep chemical equations, investigation of complex reaction mechanisms and evaluation of thermodynamic parameters, such as enthalpy (heat release/absorption) and equilibrium constants. The application interface consists of four reaction rows; each one of which is provided with the following functional elements: Multiplier: Integer value, defining how many times this reaction proceeds during the process. Recalculates stoichiometric coefficients, enthalpy and equilibrium constant after pressing done button in the keyboard! Should be changed only after balanced reaction is set. To reset, delete all digits in the field and press done button. Balance button (=): Balances the provided reaction. Ignores the already provided coefficients. Application automatically present final reaction after pressing done button in the keyboard! Does not intended to work with redox, radical and electron flow reactions, instead consider Electrochemistry app! Reaction: The field to type in reactants and products divided by =. Charge or unpaired electrons (in free radicals), if exist must be provided as well, separated by coma: Na,+ ; R,: . Application automatically presents final reaction after pressing done button in the keyboard! Swipe the field from left-to-right to reverse the reaction. Enthalpy and equilibrium constant are adjusted on the fly. Useful for investigation of complex reaction mechanisms. Application automatically presents final reaction after pressing done button in the keyboard! Keq: Equilibrium constant for particular row. Automatically recalculated after change of multiplier. Application automatically recalculates final values after pressing done button in the keyboard! Enthalpy: Should be negative for exothermic reaction (heat release) and positive for endothermic reaction (heat absorption). Automatically recalculated after change of multiplier. Application automatically recalculates final values after pressing done button in the keyboard! Important points Application supports state indexes: (g), (s), (l), (aq) – all are lowercase only, placed at the end of compound formula. Considered to be a crucial part of a molecule, so same molecules of different states appearing on the opposite sides of equation are not cancelled! Charges of molecules or unpaired electrons must be placed at the end of molecule and separated by coma. They are also considered to be a crucial part of a molecule, so same molecules that have different charges, appearing on the opposite sides of equation are not cancelled!

The GeometrySolver is not just an app, its a canvas and a book too. This app not only solves the geometric shapes, it also teaches you the formulas related to each geometric shape as well as it draws the geometric shapes when solved. This app is designed by an engineer to the perfection with every details in mind. It calculates side, height, diagonals, apothem, diameter, radius, perimeter, circumference, area, lateral area, surface area, volume. Some shapes have a dedicated interactive tab to play around and draw those shapes of different dimensions. Each geometric shape has its corresponding formulas written beautifully in mathematical way. This is a perfect app for your kids to learn geometry interactively. Draw, solve, share the geometric shapes. Drawn/solved shapes are displayed with their properties (numeric values). The Solve tab of angle is dynamic and interactive. You can touch/drag on the surface to draw an angle or use the slider to draw an angle. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There are so many common geometric shapes to learn from like square, circle, cylinder, cone, cuboid, pyramid, sphere and more There is also a Study page to help you with learning formulae related to many common geometric shapes. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
