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.
