Description
Chemistry X10 solves homework and tests.
• Is suitable for 7, 8, 9, 10 and 11 classes
• Works without Internet connection
• 800 000 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.
