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.
