Answer:
The answer to your question is pH = 1.93, acid.
Explanation:
Data
[OH⁻] = 8.6 x 10⁻¹³
pH = ?
Process
pH measures the [H⁺] concentration. The pH scale goes from 0 to 14. If the pH of a solution goes from 0 to 6.9 the solution is acidic, it the pH = 7.0, the solution is neutral or if the pH is between 7.1 and 14 the solution is basic.
1.- Calculate the pOH
pOH = -log [OH⁻]
-Substitution
pOH = -log[8.6 x10⁻¹³]
pOH = 12.06
2.- Calculate the pH
pH + pOH = 14
-Solve for pH
pH = 14 - pOH
-Substitution
pH = 14 - 12.06
-Result
pH = 1.93
3.- Conclusion
This solution is an acid.
Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.
Answer;
1) Moleculer solids; I2, S8 and P4 2) Covalent solids; SiO2; 3) Moleculer liquid; H2O 4) Moleculer gas; SO2
Explanation:
In Moleculer compounds the molecules are held together by intermoleculer forces such as van der waals forces and dipole-dipole interaction. They have weak melting and boiling point.
Covelent compounds are held together by covalent bond. They have strong melting and boiling point.

Answer:
Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
