Answer:
5.7
Explanation:
The pH can be calculated by:
pH = -log[H⁺]
Where [H⁺] is the concentration of hydrogen ions. The pH is a way to identify if the solution is an acid or a base. When pH is equal to 7, the solution is neutral, when it is less than 7, it is acid, and when it is larger than 7, it's a base.
So, for the acid solution given, [H⁺] = 2.0x10⁻⁶ M
pH = -log(2.0x10⁻⁶)
pH = 5.7
The part of the atom that accounts for electricity is the electron. As it also determines the properties.
Answer: Electrons
A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:
2NaBr + Cl2 = 2NaCl + Br2
