Chemistry AI· vs Pascal Programming Compiler

Chemistry X10 solves homework and tests. • Is suitable for 7, 8, 9, 10 and 11 classes • Works without Internet connection • 2 000 000 downloads TASKS SOLUTIONS Enter: "Given" and "Find" Result: a solved task with explanation and its answer Types of solvable tasks: • by formulas • solutions • mixtures • reaction equation • lack and excess The app does not solve tasks of derivation of the substance formula CHEMICAL REACTIONS Finds reaction equations by entered part 8000 reactions are available without internet connection TRANSFORMATION CHAINS Solves open chains Enter: Cu = CuO = CuCl2 = Cu(OH) 2 Result: 1) Cu + H2SO4 = CuO + SO2 + H2O 2) 4CuO + 2NH4Cl = 3Cu + CuCl2 + N2 + 4H2O 3) 2NaOH + CuCl2 = 2NaCl + Cu(OH)2 COEFFICIENT ARRANGEMENT Arranges the coefficients by fitting or by method of electronic balance Enter: H2 + O2 = H2O Result: 2H2 + O2 = 2H2O MOLAR MASSES Counts molar masses of complex substances. Enter: Cu(OH)2 Result: 98 g / mol. Find in the periodic table all the elements that make up Cu (OH) 2. These are: Cu, O and H ... FORMULAS FOR TASKS Formulas are divided into values parts: mass, molar mass, etc. There are prepared formulas for each of them: mass: m = nM, m = ρV and other. THE PERIODIC TABLE You can find: period, group, atom mass, class, valence, type of crystal lattice, color, temperature of melting and boiling, electronic configuration, energetic levels, electronegativity. PROTECTION FROM TEACHER: Call From Mom and Clock John is cheating on his grand test. The Teacher notices that and tries to take his phone. “Excuse me, my mom is calling”, says John and shows the screen to the Teacher. There is a phone call from John’s mom. “Go to the hall and pick up the phone”, she suggests. In the hall John taps on the lest top corner of the screen – and there is a solved task as before! He remembers the solution and comes back to the classroom. His mom didn’t call him. John has turned on protection from the teacher. There are 2 types of protection in “Chemistry X10” – Call From Mom and Clock. Clock works by default, Call From Mom is available in Pro-version. ----- “Pro-version” is a service upon monthly subscription. It gives you infinite gems and access to features which are available only in “Pro-version”: protection from teacher “Call From Mom” and detailed solution of tasks. “Pro-version” costs 1.99 USD (equivalent in local currency) per week. Subscription will be updated automatically if you don't turn off auto-extension of subscription 24 hours before current subscription expiration. Payment will be proceeded from your iTunes account during 24 hours before current subscription expiration. User can manage the subscriptions. You can turn off auto-extension after purchase in account settings. Privacy Policy: appcrab.net/privacy-policy Terms of Use: appcrab.net/terms-of-use

Write Pascal code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honor of the French mathematician, philosopher and physicist Blaise Pascal. Features: - Compile and run your program - View program output or detailed error - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting, bracket completion and line numbers - Open, save, import and share Pascal files. Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - One file can be run at a time - Some file system, network and graphics functions may be limited - This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.
