Answer:
for the reaction is -3.059 kJ/mol.
Explanation:
Reaction equilibrium:
Reaction quotient (Q) for this reaction at and is:
=
= 0.0329
We know, , where is standard free energy change, R is gas constant and T is temperature in kelvin scale.
Here, = 5.40 kJ/mol
So,
= -3059 J/mol
= -3.059 kJ/mol
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
Answer:
MgCI2+ ___ AgNO3-->___Mg(NO3)2
i think u put 2 before NO3
